Really Desperate - Sole Microsoft Global Admin Locked Out of Account

Question

Hi all,

I would be hugely appreciative of anyone who reads the below and can help me ASAP as I'm pretty desperate. Money is tight and I need to work at full capacity so I can pay the bills and feed the family.

I am the only global admin of my 365 business account. While signing up with a Password Manager app, I somehow changed the password automatically but lost track of it. The recovery email address assigned to the account is the one I'm locked out of.

I've logged a ticket (I have the reference number) and am awaiting a call back, however I use a Voip (Devyce) and sometimes it doesn't process calls from foreign numbers properly, in which case it just won't ring.

At the very least I need to change the number that I'm called back on, which I've been unable to do with the bots on customer service.

More importantly, I want reassurance the ticket is logged correctly and it won't take days, or worse weeks to be contacted, because the consequences really would be dire for me and my family.

Thanks so much in advance to anyone who helps.

Eddie
