HELP!!!: Unable to Restore Primary Account/Tenant Following Accidental Deletion of Admin - Azure Portal

Hi team, regrettable i made the mistake of deleting my global admin from my primary azure portal about ten days back. Since then i have attempted to set up a new account/tenant with the same email address as I read this is a potential way to retrieve the deleted account/tenant via the deleted user option. I also reached out to MS on several occasions however im yet to hear a peep out of them. Naturally my go to would at this point just be to start over, but i'm already hosting a single page application and i can see that this is indeed still hosted and active. So my concern is now that not only can i access this domain that i've purchased, but that i might be incurring charges that i can not control nor manage. Any help on this matter would be greatly appreciated as it is proving quite stressul. Thanks in advance and best regards.
