Hi Len,
I understand that it can be frustrating to face unexpected charges. I want to clarify that this is a user-to-user support forum, which means that the members here may not have detailed insight into your specific situation. We're all here to help each other as best as we can!
See your current subscriptions on the page https://account.microsoft.com/services first. Cancel which ones are appropriate.
Second, check all the Microsoft accounts of your Family as well if your card isn't somewhere used.
Here are the most likely causes for an unrecognized charge:
- 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.
Note: Purchases made in Candy Crush may show as MICROSOFT*CANDY CRUSH. Contact King support in the app or at community.king.com.
Use our troubleshooter to help you understand why you have been charged. Start
I hope this information helps. If you have any more questions, don't hesitate to reach out.
Otherwise, please take a moment to rate the answer. Wishing you good luck!
