I have closed a subscription and was billed for usage up to that point. I was not emailed a final invoice and when I log in I can not see any past history as the subscriptions no longer are active. I've spent hours on the phone with Microsoft who like usual have no clue what to do and just keep passing me on to somebody new until I get disconnected.
Is there a direct line to azure billing where I can get an invoice? Is there anyone who can help on this?
