Why was I charged twice for my Microsoft 365 account

Hey there! Nice to meet you!

Based on your description, kindly confirm the transaction details first by signing in to all of your Microsoft accounts in order to locate the duplicate charge on account.microsoft.com > Order History > select the date range when you received the second charge.

If it doesn't show up, the second charge may have been from a family member or a friend who might have your payment card added/linked to their accounts. Please check their accounts' Order History.

You may follow the guide through the official Microsoft website to investigate the charge from Microsoft through this link:

If you're able to find the transaction and if this is a subscription renewal from a different account, you can check if it is eligible for a refund through this link:
