Hello (Removed Name),

Thank you for contacting Xbox Email support. My name is Ben and I will be assisting you with your concern.

As I understand, you are unable to redeem the Kantus Shamen code included on the pre-ordered Gears of War 3 disc. It was telling you that the code was already redeemed.

We understand your situation as you are not the first person for this to happen to, and we offer our sincere apology by Giving you a Complimentary replacement and a Free avatar item by following this link:(Removed Link)
If you are still unable to redeem this code, then it will be best to call our customer support for further assistance. All account specific prepaid code issues need to be handled real time, over the phone for account information accuracy and security purposes. Email support does not have access to your Xbox Live account to resolve the prepaid/token code issue.
