Domain not found

[PetersonMcCoy]

I have recently set up an Office 365 Business account.  I set up the DNS to look at my personal domain and part way through the process I got kicked out of the account and can no longer log in.

The original @xxx.onmicrosoft.com isn't recognised, nor is my private domain.

I have spent hours on the phone to support, I keep getting put through to the data protection team who never answer the phone.  That's if I can get through to an advocate in the first instance.

What am I supposed to do?

So as is now, you are not able to login M365 admin center by onmicrosoft.com account?

Nope! I can’t log on to anything, when I call support the automated part of it can’t find the domain, say if I go to try and cancel the sub.

When I do get to speak to an advocate they can find the account. Also if I go to sign up a new account using my domain it says it’s taken, so the domain does exist.
