How to Dispute a Charge on an Amex Card
A step by step guide to disputing a charge on an Amex card. What to check first, when to contact the merchant, how to file online, and what happens after you submit.
A charge shows up on your American Express statement that you do not know. Or you know it, but it is wrong. Maybe you canceled a subscription and the bill kept coming. This page walks through how to dispute a charge on an American Express card, one step at a time, from the Card Member side.
Step 1: Check whether the charge is really unfamiliar
Before you dispute a charge you do not recognize, ask any authorized users on your account if they made it. A charge can look strange on a statement just because the shop's billing name is odd. A family member may have bought something and forgotten to mention it. One text message can save you a dispute you would lose.
If you share your card with others, this step comes first. For more on that, see charges on a shared card.
Step 2: Contact the merchant first
American Express asks you to contact the merchant before you open a dispute. This is not busywork. Many problems end here. A shop can fix a double charge, cancel a billing error, or send the missing item.
There is another reason to try this path. If a merchant promised a refund and gave none or only part of it, you may want to dispute the charge. A refund promise that was kept ends the problem. One that was broken gives you a clean reason to file, and a record of the promise to back it up.
Keep notes from this contact. Write down who you spoke to, when, and what they said. If the merchant refuses or ignores you, that record supports the dispute you file next.
Step 3: Gather your evidence
A dispute is stronger with proof in hand. What counts as proof depends on your reason for filing.
To dispute a charge for a canceled subscription, keep a copy of any emails confirming you canceled. For a broken refund promise, keep the emails or messages where the merchant agreed to pay you back. For a charge that never should have happened at all, keep anything that shows what you actually ordered and what you received.
Screenshots help too. A photo of the wrong item, a copy of the receipt, and the statement line itself all tell the story. Gather these before you file, not after.
Step 4: File the dispute with American Express online
American Express lets you dispute a charge online by picking it from your list of transactions. Amex's help center says you can dispute a charge by selecting the transaction and clicking "Dispute this Charge". That button is the door into the process.
The exact steps to dispute a charge can be different at each card issuer. Depending on the card issuer, you may be able to open a dispute by phone, in its app, by email or in writing. For Amex, the online path through your transaction list is the one its own help center points to.

What happens after you file: how Amex works a dispute
Once you submit, the dispute moves into Amex's own process. A disputed charge is first worked on with the Card Member before the merchant is contacted. So your first notice may be a question to you, not a fight with the shop.
If more information is needed, the merchant receives either an Inquiry or a Chargeback. An Inquiry asks the shop about the charge. A Chargeback pulls the money back and puts the shop on the spot to defend it. Either way, the merchant gets its chance to respond, and you get the outcome after that.

While you wait: payments and possible outcomes
The exact steps can be different at each card issuer, and Chase's guide gives one issuer's rules. Chase's guide says you still owe at least the minimum payment while a charge is in dispute.
The outcome can go two ways. Chase's guide says that if the bank agrees with your dispute, it reverses the charge. Chase's guide says that if the dispute finds you responsible for the charge, you have to pay it.
