An order never arrives. A hotel charges a cancellation fee although you cancelled in time. A subscription keeps billing after you cancelled. The same sentence comes up: "I'll just do a chargeback."
That works more often than people expect — not because Amex is generous, but when you take the right route, meet the deadline and attach the right documents. What follows covers a card issued in Germany, where the law below applies.
A chargeback is not a statutory right
One distinction decides almost everything: two different processes are both called a "reversal".
Case 1: You never authorised the payment. Stolen card, phished details, a charge you do not recognise. Here you have a statutory claim: under section 675u of the German Civil Code, the payment service provider has no claim to reimbursement for an unauthorised payment and must refund it without delay, at the latest by the end of the next business day. The burden of proving authorisation is theirs.
Case 2: You did authorise, but the merchant did not deliver. Non-delivery, wrong goods, a service not rendered, a double charge, an unjustified fee. There is no statutory reversal claim against Amex here — only card network rules. And with Amex, network and issuer belong to the same group, so the dispute is decided by the same side you file it with: lean, but with no independent third party.
Filing Case 2 as Case 1 — declaring your own payment as fraud — is gambling with the account: false fraud reports trigger a review and, in the worst case, closure.
The merchant first, then Amex
In Case 2, practically every issuer expects you to try to settle it directly first. That is not red tape — it creates your later evidence: a written request with date, order number, a specific demand and a deadline. For defects or non-delivery, a deadline is the precondition for withdrawing from the contract anyway. For distance purchases the 14-day right of withdrawal applies — withdrawn and unrefunded is a clean basis.
Use email or a contact form with a confirmation page, not the phone; a call is not evidence. You need not wait with obvious fraud or an unreachable, insolvent merchant.
The route at American Express
With Amex Germany, a dispute is filed on the transaction itself, not through the general hotline: open your statement in the online account or the app, select the charge and report a problem with it. A form walks you through the case type.
The questions come down to the same points: what was bought, what was agreed, what happened, what you tried with the merchant and what came of it. Write it in that order, without judgements. Three sentences of chronology plus attachments beat a page of outrage.
While the case is under review, Amex will usually credit the amount provisionally so it does not fall due — but that credit is not final. Count on weeks, not days: the merchant gets to respond, and only then is the decision made. Amex customer service can tell you the status, but does not decide the case.
The deadlines
The most common total loss is not in the reasoning but in the date.
- Immediately after you notice it. For unauthorised payments, section 676b of the German Civil Code requires notification without delay once you are aware of the charge. Leaving a foreign debit sitting for weeks puts the claim at risk even when it was valid.
- 13 months as the outer limit. Under the same provision, claims for unauthorised or incorrectly executed payments are excluded if not reported within 13 months of the debit date — the ceiling, not your working window.
- Network deadlines are shorter. Merchant disputes run under card network rules, which are much tighter than 13 months, depend on the case type and are not fully published to cardholders. So check every statement and file within days of the point where it is clear the merchant will not deliver.
With prepayments, the clock often runs from the agreed service date rather than the charge.
What not to do: claw back the Amex statement through a SEPA direct debit return at your bank. The money is back in your account, but your debt to Amex is unchanged — including dunning and a possible card block.
Which documents count
Not volume — whether a document proves something the merchant cannot deny.
- The agreement. Order confirmation, invoice or booking confirmation, with the service described, the price and the date.
- The promise that was broken. A screenshot of the delivery promise, cancellation terms or product description as of the purchase date, with URL and date visible — merchants change pages.
- Proof that nothing arrived. Tracking without delivery, or written confirmation from the carrier.
- The cancellation, with a reference number. Without a case number or confirmation email it is close to worthless.
- For returns: proof of receipt. "I sent it back" without tracking loses against "it never arrived here".
- The full correspondence. The complete thread as a PDF, not excerpts.
- For double charges: both transactions with date and amount, plus evidence that only one service was received.
What does not count: other customers' reviews, chat logs without timestamps, or the merchant being rude. With foreign currency, check the exchange rate and fee mechanics first — some supposedly wrong amounts are billed correctly.
Chargeback or insurance — not the same thing
This mix-up costs weeks. A dispute targets the payment to the merchant; an insurance benefit is a claim against an insurer attached to your card, with its own route, deadlines and forms.
Rough allocation: non-delivery, a service not rendered, an unjustified or double charge, a transaction you did not make — dispute. Damage or loss after correct delivery, a trip cancelled for an insured reason, rental car damage, delayed baggage — insurance, covered in the article on filing an Amex insurance claim and the overview of Amex insurance benefits.
Filing both in parallel achieves nothing: no double payment, just two processes waiting for each other's decision.
Typical outcomes
Four endings are realistic:
- A permanent credit. The merchant does not respond, or not convincingly — common with clear non-delivery, double charges and unauthorised transactions.
- A partial refund. Mostly where part of the service was rendered; a clean calculation of the portion you received helps more than a maximum demand.
- A re-debit. The merchant produces documents that contradict your account — a signature, proof of delivery, the cancellation terms you accepted — and the provisional credit is withdrawn. Consider beforehand what they can produce.
- Rejection. Deadline missed, no evidence of an attempt to resolve it, or a quality dispute rather than a failure to deliver. What remains is civil action against the merchant, plus a complaint to the competent dispute resolution body and to BaFin — your card terms name it.
When it is not worth it
For pure quality disputes, a chargeback is the wrong tool. "The hotel was worse than the pictures" is a question of taste or of defect rights, not a failure to deliver. Same for small amounts where the paperwork exceeds the value — a goodwill request is faster.
And with merchants you work with long term, a reversal is never free: it carries a fee and a ratio risk for them, and some ban customers afterwards. If the relationship matters more than the amount, settle it directly. More ways cardholders lose money: the overview of common credit card mistakes.
Conclusion
An Amex dispute is a procedure, not a favour. Separate the two cases first: an unauthorised payment gives you a statutory basis and should be reported immediately; a merchant dispute runs under network rules and needs a documented attempt to resolve it.
After that it is mechanical: file early, describe it chronologically, attach only documents that prove something, keep the insurance route separate. You will win the clear cases most of the time — and spot the unclear ones early enough to save the effort.
