I'm really sorry for your issues, but nothing I can tell you to help.
my recommendation is that you look for the official support channels.

or by phone..
To try recover, it is necessary that you prove that you are the owner of the tenant, and in order to recover the administrator credentials.
good luck, and if thsi help you, please don't forget to accept the answer
