What? I'm guessing you've never actually paid for an MS Support Call?

They will work through your issue no matter what until a resolution is reached.

I'm sure I don't have experience with every tier of their support, but I've dealt with both Microsoft Partner support and paid support contracts for both Windows Server and SQL Server.

They will definitely help you, eventually, and the problem will eventually get fixed. However, eventually (in my experience) has been usually several days.
