Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Matthew,
The price you indicate ($9.99) indicates that is not a Microsoft 365 Premium monthly subscription, that may be an XBox GamePass Premium subscription, check with any family member if they have signed up for that, if not, then if you do not need the extra subscription, click the Manage button beside the extra subscription and from there, you can cancel the subscription and also disable the recurring billing on the extra subscription.
