Account was removed by company, but resources still exist

I had a corporate MPN subscription account with my personal pet projects in Azure. Now I left the job and all my accounts were instantly removed. I can not auth but the resources still exist (I can connect to DB via MSSQL studio for example and the back-end is alive). Can I restore access? maybe clone everything to a personal account with different email?

Firstly I'd like to manually remove them so my personal stuff is deleted and secondly I could at least save what resources configuration I had so I don't have to recall everything from scratch next time I setup.

The exact message is:
"This username may be incorrect. Please check that you have entered it correctly. If not, please contact your administrator."

Which is no surprise, I believe the account was erased in their SSO system.
