From South African experience to a European business

Our journey began before 2018, when founder and director Mosharaf Hossain gained his first hands-on industry experience while working at his brother's mobile phone business, Ballito Cellular, in South Africa. There he learned the daily realities of device repairs, accessories retail, customer service and store operations.

In May 2018, Mosharaf formally established CelluWorld (Pty) Ltd in South Africa. Over the following years, he developed practical experience across smartphone and laptop repairs, accessories, gadgets, retail management, customer support and business operations.

Tech Rehab represents the next chapter of that journey. MB "Tech Rehab LLC" was registered in Lithuania in July 2026 to bring this operating experience into the European market through a transparent, modern and customer-focused technology business.

The director's prior operating experience includes the development and management of CelluWorld and associated technology retail and repair activities in South Africa. Tech Rehab is a separately registered Lithuanian legal entity.

How our business works

Tech Rehab generates revenue from diagnostic and repair services, repair labour, replacement parts, mobile and computer accessories, selected technology products and approved business-to-business supply arrangements.

Customers receive the applicable price or quotation before becoming financially committed. Repair work begins only after customer approval. Product orders are accepted only after stock, price, delivery availability and payment arrangements have been confirmed.

Payment channels

Depending on service availability, payments may be accepted through bank transfer, approved card-payment providers, secure online checkout or another method disclosed before the order is confirmed.

Registered business activities

• Electronic equipment repair and technical maintenance
• Retail sale of electronics, accessories and related technology products
• Wholesale trade
• Information technology and computer services

Start with the age and condition of the device

A screen repair usually makes financial sense on a device you would otherwise keep for another year or more. If everything else works well, repairing the display is normally the cheaper path.

Establish whether the damage is glass only

If the glass is cracked but the image and touch still work correctly, the repair is simpler. Black patches, coloured lines, flickering or unresponsive areas indicate that the display assembly underneath is damaged.

Do not keep using a badly cracked screen

Loose glass can cut your fingers, and cracks allow dust and moisture to reach the display and the components beneath it, which can turn a straightforward repair into a larger one.

Ask which part category will be used

Display quality varies considerably. Ask any repairer which part category they propose and what warranty applies. We state this in the quotation before you approve it.

Get it assessed before deciding

An assessment tells you what is actually damaged and what it would cost, which you can then compare honestly against the price of a replacement device.

Need it looked at?

Send the device model and a description of the fault. You will receive a quotation before you are financially committed.

Avoid running to empty repeatedly

Lithium-ion cells age fastest at the extremes. Keeping the charge roughly between twenty and eighty percent slows that ageing measurably.

Keep the device cool

Heat is the largest single factor in battery ageing. Avoid direct sun, hot cars and charging under bedding. Gaming while fast-charging also generates significant heat.

Use a good-quality charger and cable

Unregulated chargers deliver unstable power. A quality adapter and cable protect both the cell and the charging circuitry.

Check the battery health figure

Most devices report battery health or capacity in settings. Below roughly eighty percent the difference becomes noticeable in daily use.

Signs replacement is due

Sudden shutdowns while charge remains, large percentage jumps, unusual heat, or a swollen back panel. A swollen battery should be dealt with promptly: stop charging the device and contact us.

Need it looked at?

Send the device model and a description of the fault. You will receive a quotation before you are financially committed.

Switch it off and leave it off

Do not test whether it still works. Power plus moisture inside a device causes short circuits and corrosion, and powering it on is the most common way a recoverable device becomes unrecoverable.

Do not charge it

Never connect a wet device to power. Charging a damp device can permanently damage the charging circuit and the board.

Dry the outside and let it drain

Wipe the exterior, remove the case and, where the design allows, the SIM tray. Hold the device with the ports downward so liquid drains outward rather than inward.

Do not use rice, heat or compressed air

Rice achieves very little and leaves starch and dust in the ports. Hairdryers and radiators push moisture deeper and can warp components. Compressed air does the same.

Have it opened and cleaned promptly

Corrosion begins within hours and continues quietly for weeks. An early professional clean of the board is what actually saves a liquid-damaged device.

Be realistic about the outcome

Many liquid-damaged devices are recovered. Some are not. Any repairer who guarantees recovery before opening the device is not being straight with you.

Need it looked at?

Send the device model and a description of the fault. You will receive a quotation before you are financially committed.

1. Three distinct things

• Our commercial repair warranty — a voluntary guarantee we give on work we carry out.
• A manufacturer product warranty — where a product we supply carries one, provided by the manufacturer on its own terms.
• Your statutory legal guarantee — rights given to consumers by Lithuanian and European Union law.

Our commercial warranty is offered in addition to, and never in place of, your statutory rights.

2. Warranty period

The warranty period applicable to your repair is stated on your written quotation and printed on your invoice, so you always hold it in writing before you commit.

3. What the repair warranty covers

• Failure of the replacement part we supplied
• Faults attributable to our workmanship
• Recurrence of the same fault we repaired

4. What it does not cover

• New physical damage occurring after the repair
• New liquid contact occurring after the repair
• Faults in components unrelated to the work we carried out
• Damage caused by a third party opening the device after our repair
• Ordinary wear, and gradual battery capacity decline through normal use

5. Liquid damage and board-level repairs

These carry inherent uncertainty. Corrosion can continue to develop after an apparently successful repair. Where this applies to your device we explain the position before starting and state what warranty is realistic in your case.

6. Making a claim

1. Write to support@techrehab.eu with your invoice or repair reference and a description of the problem.
2. We arrange inspection of the device.
3. Where the claim is covered, we repeat the repair. Where a repeat repair is not possible or appropriate, we discuss replacement, price reduction or refund as required by law or as fair in the circumstances.

7. Products

Products supplied by us are covered by the statutory legal guarantee applicable in the European Union, and by any manufacturer warranty on its own terms. Keep your invoice.

9. Security

We apply appropriate technical and organisational measures, including access control, transport encryption for the website and restricted handling of customer devices. No method of transmission or storage is completely secure.

You also have the right to lodge a complaint with the State Data Protection Inspectorate of the Republic of Lithuania (Valstybinė duomenų apsaugos inspekcija).

11. Children

Our services are directed at adults. We do not knowingly collect personal data from children. Where a device belongs to a minor, we expect the enquiry to be made by a parent or guardian.

12. Automated decision-making

We do not carry out automated decision-making producing legal or similarly significant effects, and we do not carry out profiling of that kind.

13. Changes

We may update this policy. The effective and last-updated dates above will change, and material changes will be highlighted on this page.

1. What this website actually uses

1. Company identity

This website is operated by MB "Tech Rehab LLC", company code 308073398, a mažoji bendrija — lithuanian small partnership registered in the Republic of Lithuania, registered office Girulių g. 5, LT-12124 Vilnius, Lithuania, director Mosharaf Hossain.

2. Website use and eligibility

By using this website you agree to these terms. You must be at least 18 years old, or have the consent of a parent or guardian, to submit an enquiry or place an order.

3. Accuracy of the information you give us

You are responsible for the accuracy of the device, fault, contact and delivery information you provide. Inaccurate information may delay a quotation or make an estimate unreliable.

4. Service and product descriptions

We describe our services and products as accurately as we reasonably can. Photographs and specifications are indicative. Where a product is used or refurbished, this will be stated.

5. Enquiries, quotations and orders — what is binding and when

1. Sending an enquiry creates no contract and no payment obligation.
2. Receiving a quotation is an invitation for you to decide. It binds nobody until accepted.
3. Accepting a quotation authorises us to carry out the work described, at the price stated.
4. Placing a product order is an offer to buy, and carries an obligation to pay.
5. Our formal acceptance of the order, communicated by order confirmation, forms the contract.

Submitting a form on this website does not by itself form a binding contract.

6. Pricing, taxes and payment

Prices are quoted individually. Where value added tax applies, this will be stated. Payment methods, and any charges, are disclosed before the order is confirmed. Card payments and online checkout are not currently active.

7. Right to reject or cancel an order

We may decline or cancel an order where stock is unavailable, where a price or description error has occurred, where we cannot verify ownership of a device, or where fulfilment would be unlawful. If you have already paid, you receive a full refund.

8. Stock, delivery and risk

Delivery arrangements are not yet active. When active, delivery restrictions and estimates will be shown before the order is completed. Estimates are not guarantees. Risk passes to you on delivery. Ownership of goods passes on full payment.

9. Consumer cancellation and withdrawal

Consumers in the European Union generally have 14 days to withdraw from a distance contract, subject to statutory exceptions. See our Refund and Returns Policy and Withdrawal Form.

10. Repairs

Repairs are governed additionally by our Repair Terms and Conditions.

11. Warranty and complaints

See the Warranty Policy and Complaints and Dispute Resolution.

12. Intellectual property

The Tech Rehab name, logo, website text, layout and graphics are our property or used with permission. Third-party trademarks are identified in our Trademark Notice.

13. Prohibited use

You must not use this website unlawfully, attempt to gain unauthorised access, transmit malicious code, scrape content systematically, or submit another person's data without authority.

14. Fraud and device ownership

We may request reasonable evidence of ownership and identity. We do not service devices reported lost, stolen, blacklisted or unlawfully obtained.

15. Limitation of liability

Nothing in these terms excludes liability that cannot be excluded in law, including liability for death or personal injury caused by negligence, for fraud, or under mandatory consumer protection rules. Subject to that, our liability in connection with a service or product is limited to the price paid for it, and we are not liable for indirect or consequential loss.

16. Force majeure

We are not liable for delay or failure caused by events beyond our reasonable control.

17. Governing law and jurisdiction

These terms are governed by the law of the Republic of Lithuania. Mandatory consumer protections available to you in your country of residence within the European Union are unaffected. Disputes fall under the jurisdiction of the courts of the Republic of Lithuania, without prejudice to consumer rights to bring proceedings locally where the law allows.

18. Severability and updates

If any provision is found unenforceable, the remainder continues in effect. We may update these terms; the version in force is the one published here at the time of your enquiry or order.

19. Contact

MB "Tech Rehab LLC", Girulių g. 5, LT-12124 Vilnius, Lithuania. Email info@techrehab.eu.

1. Ownership and authority

By submitting a device you confirm that you own it or are authorised by the owner to instruct repair. We may request reasonable evidence of ownership and identity, and we do not service devices reported lost, stolen, blacklisted or unlawfully obtained.

2. Diagnostic process and fees

We inspect the device and identify the underlying fault before quoting. Any diagnostic fee will be disclosed before the device is accepted. Where a diagnostic fee applies, you will be told whether it is credited toward an approved repair.

3. Quotation and approval

You receive a quotation covering the proposed work, the part category and the price. Repair work begins only after your approval.

4. Additional faults discovered during repair

If further faults are found once work has begun, we stop and contact you with a revised quotation. No additional chargeable work is carried out without your approval.

5. Replacement parts

Depending on the device and availability we may use original, OEM-equivalent, compatible or refurbished parts. The category proposed is described honestly in the quotation before you approve it.

6. Timeframes and parts availability

Repair times are estimates provided with the quotation and depend on parts availability. They are not guaranteed completion dates.

7. Backup, passcodes and privacy

You are responsible for backing up your data before submitting a device, and for removing confidential information where possible. Some repairs require the device to be powered on and tested, which may require a passcode. We handle any access credentials confidentially and only for the requested work. We do not intentionally access personal files unless reasonably necessary for a service you have expressly requested.

8. Testing

Devices are tested after repair to confirm the reported fault has been addressed.

9. Liquid damage and board-level work

Liquid damage and board-level failures carry inherent uncertainty. Corrosion can continue to develop after an apparently successful repair, and some devices cannot be recovered. Where this applies we will explain the position before starting and state what warranty is realistic.

10. Existing damage and cosmetic change

Devices frequently arrive with pre-existing damage or previous third-party repairs, which can affect the outcome. Opening a device can cause unavoidable cosmetic change, including to adhesives, seals and water resistance. Where relevant we will tell you before proceeding.

11. Manufacturer warranty implications

Independent repair may affect a remaining manufacturer warranty. Please consider this before instructing work.

12. Repair warranty and repeat repairs

The warranty period applicable to your repair is stated on your written quotation and invoice. If the same fault recurs within that period and it relates to our work or the part we supplied, contact us and we will inspect the device and, where appropriate, repeat the repair. See the Warranty Policy.

13. Collection and return

Collection or return arrangements are agreed individually. Do not send a device before we have confirmed acceptance, the delivery method, applicable charges and the correct address in writing.

14. Uncollected devices

Uncollected devices will be handled only after reasonable written notices and in accordance with applicable Lithuanian law.

15. Repair services and the withdrawal period

Where a consumer asks us to begin a repair service during the statutory withdrawal period, we ask for an express request in the following form. This is not pre-selected and is never assumed:

16. Complaints and statutory rights

Complaints are handled under our Complaints and Dispute Resolution procedure. Your statutory rights under Lithuanian and European Union consumer law are unaffected by these terms.

A. Products

Online ordering is not yet active. When it is, the following applies to distance sales to consumers.

Right of withdrawal

Consumers generally have 14 days to withdraw from a distance purchase without giving a reason, subject to the statutory exceptions in law. The period generally begins on the day you, or a person you nominate, take physical possession of the goods.

How to notify us

Send a clear statement to support@techrehab.eu or use our Withdrawal Form. Please wait for the confirmed return address before sending anything back.

Condition of returned goods

You may handle the goods as you would in a shop. You may be liable for any diminished value resulting from handling beyond what is necessary to establish the nature, characteristics and functioning of the goods.

Costs

Unless we state otherwise, you bear the direct cost of returning the goods. We reimburse the price paid together with the standard delivery cost you originally paid; where you chose a more expensive delivery method, we reimburse the standard rate.

Refund timing and method

We reimburse without undue delay and no later than 14 days from the day we are informed of your decision to withdraw, using the same means of payment you used, unless you expressly agree otherwise. Where legally permitted, we may withhold reimbursement until we receive the goods back or you supply evidence of return, whichever is earlier.

Exceptions

Statutory exceptions may apply, for example to sealed goods unsuitable for return for health protection or hygiene reasons where the seal has been broken after delivery, and to goods made to your specification. Any exception will be identified before you order.

B. Repair services

Cancellation before work begins

You may cancel a repair before work begins. Any diagnostic fee already disclosed and incurred may remain payable.

Cancellation after work has begun

Where you expressly requested that the service begin during the withdrawal period, you may be required to pay an amount proportionate to the work properly performed before cancellation.

Special-order parts

Where a part has been specially ordered for your device, we will tell you before ordering whether the cost is recoverable if you cancel.

Unsuccessful repairs

If a repair cannot be completed, we explain what was found and what was chargeable. Depending on the circumstances this may result in a repeat repair, a price reduction or a refund. Each case is assessed individually and we do not guarantee a refund in every unsuccessful repair.

C. Faulty or non-conforming goods

Separately from any withdrawal right, consumers have statutory rights where goods do not conform to the contract, including repair, replacement, price reduction or rescission in the circumstances set out in law. These rights are not affected by this policy or by any commercial guarantee.

D. Cancellation process

1. Contact support@techrehab.eu with your order or repair reference.
2. We acknowledge and confirm the return address where goods are involved.
3. You return the goods, where applicable, in the condition described above.
4. We inspect and process the refund.

E. Refund process

Refunds are made to the original payment method within the statutory period. We will confirm by email when a refund has been issued.

We do not operate a "no refunds" or "all sales are final" policy. Statutory consumer rights always apply.

Model withdrawal statement

You may use the form below, write to us directly, or print and post the statement above. Any clear statement of your decision is sufficient.

Complete and send

1. Current position

Courier arrangements, served countries, delivery charges and delivery times have not yet been finalised, so none are stated here. We will not publish delivery information until it is real and operational.

2. Do not send devices to the registered office

Girulių g. 5, LT-12124 Vilnius is our registered office and legal correspondence address. Customer visits and device deliveries are available only by prior arrangement and confirmation. It is not currently a parcel-receiving address. Contact us first and we will confirm in writing where, whether and how a device may be sent.

3. What this policy will cover once active

• Countries served and any delivery restrictions
• Order processing times and delivery estimates
• Shipping charges and how they are calculated
• Accepted couriers and tracking
• Failed deliveries and incorrect addresses
• Lost or damaged parcels and transit risk
• Insurance arrangements
• Customs and import charges for destinations outside the European Union
• Returning products to us
• Sending devices to Tech Rehab, including packaging instructions
• Return of repaired devices

4. Packaging guidance for future device shipments

When device shipping becomes available, we will provide packaging instructions before you send anything. As a general principle, devices should be powered off, protected against impact and moisture, and sent by a tracked and insured service.

5. Contact

To arrange anything involving delivery, write to support@techrehab.eu.

1. Independent repair business

Tech Rehab is an independent repair business and is not affiliated with, sponsored by, endorsed by, certified by or authorised by Apple, Samsung, Google, Huawei, Xiaomi, Oppo, Vivo, Motorola, Microsoft or another manufacturer unless expressly stated with verifiable evidence.

2. Use of brand names and logos

Apple, the Apple logo, iPhone, iPad, MacBook, Samsung, Galaxy, Android, the Android robot, Google, Pixel, Huawei, Honor, Vivo, Oppo, Xiaomi, Redmi, Motorola, OnePlus, Nokia, Dell, HP, Lenovo, Asus, Acer, MSI and Microsoft are trademarks of their respective owners.

Brand names and logos are used on this website only to identify the devices we are able to service. Their use does not imply partnership, sponsorship, approval or authorisation by the trademark owners.

3. Descriptions we do not use

We do not describe ourselves as an Apple Authorised Service Provider, Samsung Authorised, a certified repair centre or an official partner, because we hold no such authorisation. We describe our work as professional independent repairs.

4. Replacement parts

Where a replacement part is not an original manufacturer part, this is stated honestly in the quotation before you approve the work.

5. Contact

If you are a trademark owner with a concern about the use of your mark on this website, please contact us and we will respond promptly.

1. Our commitment

We want this website to be usable by as many people as possible, including people using screen readers, keyboard navigation, magnification or reduced-motion settings.

2. Measures taken

• Semantic HTML headings and landmarks
• A skip-to-content link at the start of every page
• Visible keyboard focus indicators
• Labels associated with every form control, and required fields marked in text as well as colour
• Alternative text for meaningful images, and decorative graphics hidden from assistive technology
• Colour contrast checked against WCAG 2.2 AA for body text and interface elements
• Full support for the operating-system "reduce motion" setting, which disables the animations on this site
• Layout that reflows without horizontal scrolling down to 320 px width
• No time limits, no auto-playing audio and no flashing content

3. Conformance

We aim to meet the Web Content Accessibility Guidelines version 2.2 at level AA. This is an ongoing effort and we do not claim formal certified conformance.

4. Known limitations

The decorative repair animation conveys no information that is not also given in text. Where a browser blocks the opening of an email application, the enquiry and withdrawal forms provide the destination address in text so the same action can be completed manually.

5. Feedback

If you encounter an accessibility barrier on this website, please write to info@techrehab.eu describing the page and the difficulty. We will respond and work to correct it.

Step 1 — Contact us

Write to support@techrehab.eu and include:

• Your name
• Your order or repair reference number
• A description of the problem
• Any evidence or photographs
• The resolution you are seeking

Step 2 — Acknowledgement and investigation

We acknowledge your complaint and investigate it within a reasonable period. We may ask for further information or to inspect the device. We will tell you the outcome and the reasons for it.

Step 3 — If the matter remains unresolved

If we cannot resolve the complaint between us, consumers may contact the competent Lithuanian consumer-protection body, the State Consumer Rights Protection Authority of Lithuania, or use another dispute-resolution mechanism legally available to them. You may also pursue the matter through the courts.
