Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
Microsoft has a dedicated article on this:
How to investigate a billing charge from Microsoft
- A Microsoft subscription has recurring billing enabled.
- Someone you know, such as a family member, bought something with your card. You can now investigate this on the Manage your payments page.
- A previously declined charge was charged again.
- A pre-order or split order was shipped.
- Someone made an in-app purchase from an app, game, or office.
On this account, do you see a 365 service active at https://account.microsoft.com/services page?
Use this troubleshooter to help you understand why you have been charged - it should route you to an agent too, since this is a user-user support forum:
I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
