Try to contact Microsoft support immediately.

Don't rely on the distributor/vendor, they act very slowly.

You're a customer of Azure, you can contact them by any mean, the fact you pay through a distributor doesn't change that relationship.

So I would open a Azure support, and also will try to find Azure team on Twitter/Hacker News etc and contact them politely for help.

There is no way you would have to pay this bill. They will sort out something or even waived it if it's the first time.
