You saw a charge on your Discover card that looks wrong. Here is how to dispute a credit card charge with Discover, step by step, and what to expect along the way.

When you can dispute a Discover charge

Discover lists three common reasons to dispute a charge. One is an unauthorized charge, meaning a charge you did not make and no one allowed on your account made. Another is a billing error, such as being charged twice or charged the wrong amount. The last is goods that never arrived.

Before you dispute a charge you do not recognize, ask any authorized users on your account if they made it. Bank of America says many disputed charges are real charges that people do not recognize or remember.

If a merchant promised a refund and never sent it, or sent only part of it, you may want to dispute the charge too. The same goes for a canceled subscription that keeps billing you. Keep a copy of any emails confirming you canceled.

Before you dispute: contact the merchant first

Discover says you should try to settle the problem with the seller before going to your card issuer. Chase's guide says a merchant may fix a charge error in a few days, while a bank can take weeks.

There is one exception worth knowing. Regulation Z says a cardholder need not contact the seller first about goods or services not delivered as agreed.

Either way, save the merchant's reply. It shows you tried, and it can help your case.

How to dispute a Discover credit card charge

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.

One more thing. Regulation Z gives the cardholder 60 days to get a written notice to the card issuer. That clock starts when the issuer sends the first statement that shows the error. If you are close to that deadline, file in writing right away rather than waiting on the merchant.

What information and documents you need

Regulation Z says the notice must let the card issuer identify the cardholder's name and account number. It should also give the error's type, date and amount, and why you think it is wrong.

Pull together your proof before you file:

the receipt or order confirmation
photos of what arrived, if something came but was wrong
messages you sent the merchant, with dates
a note of any calls you made, with the date and what was said
proof of a cancellation or refund promise, if you have one

Keep copies of everything you send. For a fuller checklist, see what to do before you dispute a charge.

What happens after you file a dispute

Regulation Z says the cardholder need not pay the disputed amount or its related charges during the dispute. It also bars the card issuer from trying to collect the disputed amount during the dispute, such as in court. And it bars the issuer from reporting you as late for not paying that amount. The issuer may report that an amount is in dispute.

Keep paying the rest of your bill as normal.

How long a Discover dispute takes

Regulation Z gives the card issuer 2 complete billing cycles after it receives the notice to resolve the error. It must resolve the error no later than 90 days after it receives the notice.

Your rights under the Fair Credit Billing Act

The Fair Credit Billing Act is the federal law on correcting billing errors. Regulation Z says a charge not made by the cardholder or someone allowed to use the card is a billing error. It says a charge for goods or services not accepted or not delivered as agreed is a billing error too.

The law also sets standards for how the issuer decides. Regulation Z says a card issuer must do a reasonable investigation before it finds there was no error. If it finds the error, it must fix it, credit the account and send a correction notice.

What to do if you disagree with the outcome

Regulation Z says a card issuer that finds no error must explain why in writing. It also says the card issuer must send copies of its proof if the cardholder asks. So ask. Read the papers and see what the merchant sent.

The Consumer Financial Protection Bureau says a charge already paid can still be disputed. It also says money already paid likely comes back only after the card company agrees with you.

No one can promise a dispute will win. But a clear claim, good proof and a timely filing give you your best shot. To see how a chargeback works, read what is a chargeback.
