Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Sorry to hear you're experiencing this issue. To confirm whether these charges are from Microsoft, please check your order history here: https://account.microsoft.com/billing/orders
If you don't see any purchases on that account, check any other Microsoft accounts you may have used in the past.
If you still can't find the charges on any of your accounts, you'll need to contact your payment provider. It's possible that someone else has access to your payment method and is making the charges appear as though they are from Microsoft.
