Global Administrator locked out of AAD

Hello,
Years ago, I created a "Azure Active Directory (self-service)" account to enable me to use PowerBI. It had the same email address as my personal Microsoft Account, which is the one I want to prevail. I was thinking to try to delete the account and the directory from Office.Com and Azure.Com as they were getting in my way. I found that I wasn't the Global Administrator for the AAD and managed to follow the instructions to become the administrator by creating a TXT record on the DNS entry. I then tried to continue along the path of deleting the domain, but still wasn't able to do so as my account had an email address with the domain. I changed the email address to the @keyman .onmicrosoft.com version and got booted out. Subsequently, I haven't been able to log back in and get the "incorrect password" message. I hadn't got any password recovery mechanism setup and thus am stuck where I cannot get back in. I thought I might try creating a new self-service account, which was successful and I can login to the AAD again, but only as a user and not an administrator. I thought I might be able to try the same trick to become administrator again, but when I visit https://portal.office.com/admintakeover while logged in as the new user I get an authorisation failure (probably rightly so).

So I am now stuck.

In the shorter term, I wanted to delete the AAD and all traces of it so that I can use things like Teams on my personal Microsoft account.
In the medium term, I want to to start again with the domain in Azure and add something like Microsoft 365 Business Basic or possibly Microsoft 365 F3 and migrate my on-premises Exchange to it. I would want to join my local domain (which is a .local) to the AAD and have synchronisation from my local domain controller to AAD to enable my users to login to Exchange seamlessly (ie no additional credentials). I would then make use of Teams etc.

Can anyone help me to get the locked out global administrator user in AAD back in again. I tried calling support this morning and spoke with several people, none of whom really were able to help.

Many thanks
Graham Cottle

    Contact O365 support team, they can unblock/elevate an existing non admin account to GA from backend.
