Why am I paying Microsoft subscription?
One possible cause of this issue could be that someone else has used your credit card information to create a Microsoft account and has been using it to subscribe to our services.
How do I find out why Microsoft is charging me?
Turn recurring billing off
On the Services & subscriptions page, locate your Microsoft 365 subscription and then select Manage. Do one of the following: If you see a Turn off recurring billing link, choose it to turn recurring billing off. If you see a Cancel link, choose it to cancel the subscription.
How do I stop Microsoft from charging my account?
There are no fees for having a Microsoft account, putting money into it, or using it to buy stuff from us. In other words, it's free!
