Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hey there! Nice to meet you!
I'm sorry you are experiencing this.
Based on your description, the hacker was able to remove the account's primary email address/security info and replace it with their own email address.
Since the security info has been replaced by the hacker, I'm afraid there is no other working method to recover the Microsoft account, and Microsoft Support cannot help either.
Unfortunately, it is not possible to transfer the subscription from one account to another.
As for the recurring subscription, you'll need to contact your financial institution/bank directly and request to freeze all charges from Microsoft, cancelling the subscription on its renewal in the process and preventing any unauthorized purchases.
You may also need to have your card blocked and request a new one.
Thank you for your understanding.
Best regards,
Darhyl
