Dear @Dominic_Knight,
Good day! Welcome to Microsoft Q&A forum!
Based on your description, I understand that you have been locked out of your Global Administrator accounts in the Microsoft 365 admin center for the past three days. You were advised yesterday morning that you would receive a callback within one hour; however, that callback did not occur, and it is now the following day. Additionally, you have attempted to follow up via email but have not received any response.
I sincerely apologize for the inconvenience caused by this issue.
Regarding your situation, I have sent you a Private Message about this matter.
Please kindly check it as shown below:
Thank you for your time and patience!
