The two different amounts cannot be identified as duplicate billing from the statement alone; sign in to your Microsoft account’s payment page and use Investigate to match each charge to its purchase or subscription.
Identify both charges
- Open Manage your payments, sign in, and select Investigate beside the payment method.
- Open Order history.
- Select Payment & billing > Order history, set the date range to include 26 July and 14 October, and look for orders marked Completed or Redeemed. Open Order details to compare the description, amount, and payment method with your bank statement.^1^
- If you use more than one Microsoft account—such as Outlook, Hotmail, Live, or another email registered as a Microsoft account—repeat the order-history check in each account.
Different amounts may indicate separate subscriptions or purchases rather than the same charge. Other documented possibilities include recurring billing, a purchase by a family member using the card, or collection of a previously declined payment.^2^
If one charge remains unexplained
Use Contact Microsoft Support, enter Unrecognized Microsoft 365 billing charge, select Get Help, and then Contact Support. Have these details ready:
- Charge dates: 26 July and 14 October
- Amounts: $179 and $109
- Statement descriptions
- Order numbers, if shown
- Last four digits of the payment card
If Microsoft cannot locate the charge under any account and you do not recognize it, contact the bank or card provider promptly. Ask it to protect the payment method against further unauthorized charges, not merely dispute the existing transaction.^2^
If it is an unwanted renewal
Check the subscription’s eligibility before cancelling. Microsoft states that the most recent recurring charge may qualify for a refund when cancellation occurs within 30 days of payment, subject to account, product, region, and one-time eligibility conditions.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")
Do not post card numbers, account email addresses, or transaction identifiers in this public forum.
