I have an unauthorized charge on my checking account

Contact your bank immediately to report the unauthorized debit, prevent additional charges, and ask whether the checking account or debit card should be blocked or replaced.

Contact a Microsoft representative

1. Sign in to the Microsoft account that may be associated with the charge.
2. Open Manage your payments.
3. Find the unrecognized transaction and select Investigate.
4. If it cannot be identified, open Contact Microsoft Support.
5. Enter Unauthorized billing charge, select Get Help, and then select Contact Support.
6. Choose the available agent option. For personal Microsoft accounts, this commonly begins with live chat; you may then be offered a callback. Microsoft recommends this escalation path for charges that remain unresolved after investigation.^1^

Have these details ready, but enter them only in Microsoft’s secure support flow:

• Charge date and amount
• Exact transaction description shown by the bank
• Last four digits of the affected payment method
• Any Microsoft accounts that might have used it

Do not post bank-account or card details in this public forum.

Check other possible accounts

If the charge is absent from your account, check any other Microsoft accounts you use and ask household members whether the payment method is attached to theirs. An unrecognized charge can be associated with recurring billing, a family member’s purchase, a retried charge, or an in-app purchase.^1^

If neither you nor Microsoft Support can identify the transaction, continue the fraud dispute with your bank. Microsoft specifically warns that disputing only the existing charge may not prevent another debit, so tell the bank that the payment information may be compromised.^1^
