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, Médiateur bancaire de votre banque / Médiateur de l'AMF (0 811 901 801) — the financial ombudsman for France — decides for free and the lender must follow. ACPR / AMF — Assurance Banque Épargne Info Service (0 811 901 801) licenses lenders and takes complaints about unlicensed or predatory lending, hidden costs and unfair terms. SignalConso — DGCCRF (0809 540 550) 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 Médiateur bancaire de votre banque / Médiateur de l'AMFFree, in writing, binding on the lender up to a limit. Attach the complaint and the answer.
- Unlicensed lender: ACPR / AMF — Assurance Banque Épargne Info ServiceCheck 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.
