A cloud-based identity and access management service for securing user authentication and resource access
Hey there, LPS
I am sorry you are experiencing trouble trying to get through to support through phone support. When I have tried phoning support in the past, the bot doesn't always understand you. I have updated your question tags so it is in a better place for visibility. If you are locked out of your only admin account, a Microsoft external staff moderator is able to private message you and collect information to forward to Microsoft's data protection team, so they can reset your MFA.
From reading your question, you are unable to log into the only admin account due to MFA. When you say it is not verified, please can you tell me what you mean by this?
Thanks,
Nathan
