Important Safety Warning: Beware of fake customer service numbers on search engines. Only use official channels. Scammers frequently buy ads to promote fraudulent phone numbers. Temu operates almost entirely digitally in the UK and does not heavily advertise an inbound customer service phone number. Staff will never ask for your account PIN, ask for your bank details via text message to “release a customs package,” or ask you to move money to a “safe account”.
Level 1: Customer Support (Initial Complaint)
-
How to complain: You must raise your complaint via the “Customer Service” portal on the Temu app or website. Navigate to “Your Orders,” select the specific item, and use the automated prompts to report a missing, damaged, or “not as described” item. This will usually trigger the Live Chat or a support ticket.

Source Verification Note: Temu UK Help Portal
-
Availability: The automated chatbot and ticketing system operate 24 hours a day, 7 days a week.
-
Timeline: Temu aims to respond to initial digital tickets within 24 to 48 hours. Many low-value refunds are processed automatically by their system without human intervention.
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If the automated system or standard customer service refuses your refund (e.g., claiming a parcel was delivered when it wasn’t), you must formally escalate it. Reply to your existing ticket, demand a “Human Agent” or supervisor, detail a clear timeline, and provide any photos/evidence.

Postal Complaints Address: Customer Service Department, Whaleco UK Limited, 10th Floor, 5 Churchill Place, London, E14 5HU
-
Timeline: If they flatly refuse your request in writing (via the chat transcript or email), you have exhausted their internal process and can proceed immediately to Level 3. You do not need to wait 8 weeks.
Level 3: Regulatory Authority (The Financial Route)
-
Authority: Your Bank OR Klarna/Clearpay
-
The Reality: Because Temu is not part of any statutory Ombudsman scheme, you cannot escalate a retail dispute to an external regulator. Your path depends entirely on how you paid:
-
Standard Debit/Credit Card: If Temu refuses to refund you for faulty, missing, or counterfeit goods, you must immediately contact your bank and claim a breach of contract under Section 75 of the Consumer Credit Act (for credit cards) or request a Chargeback (for debit cards). Use your chat screenshots as evidence that the merchant refused to help.
-
Source Verification: Financial Ombudsman - Section 75 Guidance
-
Buy Now, Pay Later (Klarna/Clearpay): If you used a BNPL service at the Temu checkout, you must log into that specific BNPL app and “Pause” the payment, reporting a dispute with the retailer. Klarna/Clearpay will then temporarily freeze the invoice and investigate the return/delivery issue directly with Temu on your behalf. If the BNPL provider fails to resolve the financial dispute fairly, you can escalate them to the Financial Ombudsman Service (FOS).
Level 4: Legal Action (Final Step)
-
Pre-Litigation: Before commencing legal proceedings, UK legal protocols require you to send a formal “Letter Before Action” (LBA). You must address it to their exact corporate legal entity operating in the UK: Whaleco UK Limited.
-
Legal Address: Legal Department, Whaleco UK Limited, 10th Floor, 5 Churchill Place, London, E14 5HU
-
Court: If the LBA fails and your bank refuses a chargeback, you can file a lawsuit. For financial claims up to £10,000 in England and Wales, you can use the Money Claim Online (MCOL) portal to enter the Small Claims Track.
