Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Linda C,
Thank you for reaching out to the Microsoft Community. My name is Raymond and I'm happy to help.
Sorry for this inconvenience. In order to find the Microsoft account associated with your Microsoft 365 subscription, you need to check the Services and subscription page of all your accounts. Use link: https://account.microsoft.com/services
If you are unable to find the associated account, do you have any proof of this purchase? Perhaps an email that can be provided to Microsoft?
If you do, I will recommend you contact Microsoft support via live chat for further assistance. Kindly go to Microsoft Contact Us website:

Please let me know if you need more assistance.
