Folks, don't mistreat the OP. He is voicing a valid complaint with the Lumia 920: support. I just talked to a friend who switched to the Lumia 920 in Canada after buying the last 4 iPhones. His call quality is problematic, sounds like it might be a dud, and he is disappointed that he will have to mail the phone away instead of walking into the Apple store as he used to be able to do. Support is not the only factor in buying a phone, but it is a factor and for many people a serious one.
I think instead of nokia opening shops there should be more of a presence with Windows/Microsoft shops. I know there is a few, but here in the uk you would think a presence in London, Birmingham, Manchester, Glasgow and Edinburgh would be a good start.
