Even when you have an expensive contract with Microsoft and a direct account manager to help you run the gauntlet you still end up having to deal with awful support people.

Years ago at a job we were seeing issues with a network card on a VM. One of my coworkers spent 2-3 days working his way through support engineer after support engineer until they got into a call with one. He talked the engineer through what was happening. Remote VM, can only access over RDP (well, we could VNC too, but that idea just confuses Microsoft support people for some reason.)

The support engineer decided that the way to resolve the problem was to uninstall and re-install the network card driver. Coworker decided to give the support engineer enough rope to hang themselves with, hoping it'd help him escalate faster: "Won't that break the RDP connection?" "No sir, I've done this many times before, trust me" "Okay then...."

Unsurprisingly enough, when you uninstall the network card driver and cause the instance to have no network cards, RDP stops working. Go figure.

Co-worker let the support engineer know that he'd now lost access, and a guess why. "Oh, yeah. I can see why that might have been a problem"

Co-worker was right though, it did finally let us escalate further up the chain....
