Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi, I'm John!
Since she no longer has access to the account or email, you won’t be able to cancel it from the Microsoft side directly.
The best course of action is to contact the bank/card provider. Ask them to block future charges from Microsoft. Dispute the charge (explain the account is no longer accessible and unused). Of possible, request a replacement card.
This stops any recurring billing tied to the old card.
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
