Can you get it online without contract? I know when I was selecting my Lumia 920 there was a option to change to 1yr or No Contract. If you can, take a print screen and bring it in.

Sadly, I am also having major issues with very poor support; though my problems have been with phone support. I am also worried about signing up for 2yrs after dealing with them this last week and a half trying to setup as a new client.
