Locked out of Azure tenant – only Global Admin, lost MFA access

Hi,

I have lost access to my Azure account due to lost MFA. I tried calling support and different other contact methods proposed by Copilot but non of them worked. I understand this can be only dealt with only through support but since this is a private account I cannot get to talk to any real person or agent that can help me.

Can you please advise what are my options?

Thanks!
