Support information:
When you can't log into your account or the admin portal, you'll need to call Microsoft support for help. The numbers are in this article:
You will need to contact the Microsoft Data Protection team for assistance with this issue. The Data Protection team is specifically equipped to handle these matters, verify the required information, and take the appropriate action to resolve your issue. They will need proof you control the domain name.
Call during your country's business hours. If you get the phone bot (and not immediately told to use the admin portal) make sure you ask for the data protection team and say "I cannot access admin center and I am the only admin user".
