Should I wait if one charge is still pending?

Usually yes for a few business days. A pending hold often drops off by itself. If it later posts as a second charge, ask for reversal then.

What does a reversal of a duplicate transaction mean?

A reversal cancels a charge that should not have posted. The merchant or your bank sends the amount back to the original payment method, and it can take several business days to appear.

What if the merchant says both charges are valid?

Ask for the order reference or invoice for the second charge. If they cannot produce one, send the same request to your card issuer as a written billing-error notice.

Key facts

Pending vs posted: A pending authorization is a temporary hold. Only a posted second charge needs a reversal request.
US credit card: Written notice to the billing-error address within 60 days of the statement. Issuer confirms in 30 days, then has two billing cycles to resolve.
While disputing: You do not have to pay the disputed amount or related finance charges, but pay the rest of your bill on time.
US debit card: Notify your bank within 60 days. It generally has 10 business days to investigate before provisionally crediting you.

01
Verify that it is a real duplicate
Check whether the second charge is a pending hold, a separate order, a split shipment, or a settled duplicate. Only the last one is a billing error.
02
Put both charges side by side
Screenshot or copy the two statement lines with date, amount, and merchant descriptor, next to the one order confirmation.
03
Ask the merchant to reverse one charge
Name both charges and the single order, ask for reversal of the second by a calendar date, and keep the issuer deadline in view.

Duplicate charge letters: fill in your details and copy

Ask the merchant first. The third template is a written billing-error notice for your card issuer.

01Reverse the duplicate (merchant)

Hello, I was charged twice for order [order number]: [amount] on [charge date] and [amount] on [second charge date]. I placed one order.

Both charges have posted to my account. Please reverse the second charge to my original payment method and confirm which transaction will be refunded by [date you expect an answer].

02Follow-up with a deadline

Hello, I wrote on [date of first message] about a duplicate charge of [amount] for order [order number] and the second charge is still on my account.

If you believe both charges are valid, please send the order reference for the second one. Otherwise please reverse it by [final date], or I will dispute it with my card issuer.

03Written billing-error notice (card issuer)

To the billing disputes department: I am writing to dispute a billing error on my account. My name is [your name], and the account ends in [last four digits].

The statement dated [statement date] shows two charges of [amount] from [merchant], on [charge date] and [second charge date], for a single order ([order number]). The second charge is a duplicate.

Please correct the error, credit any related finance charges, and send me written confirmation. I enclose the statement lines, the order confirmation, and my correspondence with the merchant.

How this works

First confirm that both charges have posted, because a pending hold usually drops off by itself. Then ask the merchant to reverse one in a message that lists both statement lines. If it does not fix it quickly, send your card issuer written notice: for a US credit card the deadline is 60 days from the statement that shows the error.

What is a duplicate charge?

A duplicate charge is when the same merchant bills you more than once for one purchase: same amount, close timing, one order. It differs from two real orders and from a temporary hold.

Pending authorization: a temporary hold that usually disappears after a few days. It is not yet a final charge.
Settled duplicate: both amounts have posted. This is the case to ask the merchant or issuer to reverse.
Reversal: the merchant or bank cancels a posted charge and the money returns to your original payment method, which can take several business days to show.

Merchant first, or the bank?

Ask the merchant first for a quick fix, but do not let that use up your issuer’s deadline.

Write to the merchant with both statement lines and ask for reversal within a few business days.
If there is no fix, or the merchant says both charges are valid without an order reference to support it, write to your card issuer.
For a US credit card, send the written billing-error notice to the address printed for billing errors, not the payment address, and include your name, account number, and a clear explanation. Keep a copy.
Keep paying the undisputed part of your bill while the dispute runs.

Before you send, and when to escalate

Before you send

Confirm both charges are posted, not pending, before you write.
Write the amounts and dates of both charges in the first lines of the message.
Use the billing-error address on your statement for written notice, not the payment address.
Note the statement date: it starts your 60-day clock for a US credit card.

Escalate when

Both charges posted and the merchant cannot tie the second to a separate order.
The merchant delays without an order reference or explanation.
About 45 days have passed since the statement showing the charge and it is still not fixed.
