That's strange. I've had nothing but great things to say about Surface and Microsoft Store support.
I've heard that "I'll personally get back to you" from the US team, which they never did. That's because English is my first language, being from the US and all. Now I'm living in Spain, and I've been contacting the Spanish team ever since and every time they say that they'll keep me in the loop, they do. Sometimes they even call me just to make sure I'm happy with my order!
I'm very sorry about your bad support. It's funny because I think the US team is the bad egg. I am SO happy with the Spanish team. They're top and always do what they say they'll do and keep me apprised of the situation.
