Can't Play The Game - Preview Disc

Ive already looked this problem up and I saw that they gave out codes to the people that were part of the preview disc and emailed them out. Well this is my first time loading up the game since that September update and I never got any email or even info about this issue or codes. I have gone through all my old emails and theres nothing there. I have contacted xbox support and they basically said too bad you are too late, they have given out the codes already. I feel that is really bad business, there should not be an expiration on the error caused by you. So I would like to know if there is still a way for me to get a code because I am not going to go waste 30 bucks on a used game that I already have.

Xbox Support are utterly useless.

PM bs angel and she will sort you out, keep in mind it may take a bit, she is away at E3 right now.
