A loan, credit card or buy-now-pay-later company treats me unfairly — who do I contact?
Every lender must have a complaints procedure and answer within a fixed deadline, so start there in writing. When they refuse, ignore you or the deadline passes, CSSF — réclamations clientèle (26 25 1-1) — the financial ombudsman for Luxembourg — decides for free and the lender must follow. ULC — Union luxembourgeoise des consommateurs (49 60 22 1) licenses lenders and takes complaints about unlicensed or predatory lending, hidden costs and unfair terms. Service d'information et de conseil en matière de surendettement (SICS) (49 83 33 1) helps with your rights as a consumer, such as the 14-day withdrawal from any credit agreement.
🗣️ What to say
"I make a formal complaint about agreement [number]. [The interest / fee / charge] was not disclosed clearly / is not in the contract / the payment plan was changed without my consent. I ask you to [refund / correct] within the legal deadline and to confirm in writing."
🪜 Step by step
- Complain to the lenderIn writing, with the word "complaint". They must answer within the legal deadline (often 15 working days, up to two months).
- Check the paperworkPre-contract information, total cost of credit, APR — missing or misleading information can make fees unenforceable.
- Withdrawal rightAny consumer credit can be cancelled within 14 days without reason, repaying only the capital and interest for the days used.
- Escalate to CSSF — réclamations clientèleFree, in writing, binding on the lender up to a limit. Attach the complaint and the answer.
- Unlicensed lender: ULC — Union luxembourgeoise des consommateursCheck the register. An unlicensed lender cannot enforce interest and may not enforce the loan at all.

❓ Frequently asked
Buy-now-pay-later counts as credit?
Yes since the 2023 consumer credit rules: same complaint rights, same ombudsman, and the fees must be disclosed up front.
They added a "late fee" I never saw
A fee not in the contract cannot be charged. Dispute it and complain; the ombudsman removes these routinely.
Can they take money from my account?
Only with a valid direct-debit mandate you gave. You can revoke the mandate at the bank and reverse unauthorised debits.
