I get some error when deleting an azure service so I put a support ticket asking for help. Just as I am about to close my computer for the day I receive an email saying:

"Product team will disable the account xxxxx from backend".

The xxxxx is our subscription number. The subscription that hosts not only that service but also production servers and databases, storage accounts containing backups, etc.

I replied to the email so hopefully disaster is avoided otherwise tomorrow wont be a happy day.
