KiltedTim this particular phone store wouldn't even rectify things 1 day after purchase when I discovered there was a BOGO promotion that they didn't give to me and on day 3 when I was told my software was corrupt they wouldn't fix that either.. So a year and a day later when I discover that the imei number on my purchase receipt and box don't match the device, I can for sure guess what their response would be!!
You take it back to wherever you bought it and demand a refund.
Nothing we as users can do to help you. It appears you didn't purchase from Apple, so you'll have to deal with whoever you did purchase from.
