Account recovery

I've been locked out of my main account for over 45 days now and everything important is linked to that email.  I can't log in to many other things that send verification codes to my Microsoft email because it seems impossible to recover my Microsoft email. I have access to my security backup email but because I had 2 factor authentication turned on I need access to the authenticator app which is on my old phone or a 25 digit recovery code I can't find. I tried the account recovery form but because of 2FA it tells me I can't recover an account with 2FA enabled. I then tried the security information replacement which is a 30 day process to replace my old security info I no longer have access to with a new backup email.

I received a confirmation that the 30 day replacement process started and a reminder at 15 days giving me an exact date and time that my new security information will replace the old information. The deadline arrived and nothing happened. I then contacted support the next day and they assured me there can be a delay up to 48 hours. I waited the 48 hours and still nothing happened.  I've been in contact with support now almost daily and spoken to supervisors that have even taken control of my computer and recorded the issue. I'm now locked out of my account for a total of around 45 days and now 36 days into the 30 day deadline for replacing my old security information. I've even filled out forms that I was advised to fill and submit and in response I was just told to keep trying to "recover my account". But I can't "recover" my account because it had 2FA enabled.  No one seems to be able to help even with escalations to the security team.
