Hi,
Ideally you should have another account as a backup in case the primary account have issues, it is known as breakfix account. However in this instance if you are the only admin of the tenant the only way to recover is to call up global numbers and provide the ownership and identity proof of the tenant that you own it.
In this case you need to call up the support desk and provide the identity proof as the Data Identification team will cross check the details you provide with the account
Hope this helps.
