I took Microsoft up on their offer to re-up my XBOX Live Gold subscription in February and get a free copy of one of three games, and was told that I would receive an email telling me how to claim my game. After not having received anything, I contacted support, and after being passed around for a week was eventually told that the promotion had ended, and since I hadn't called to question the missing email and game quickly enough, I can now not expect to receive my promised promotion, or any other kind of recourse.
What this essentially amounts to is Microsoft saying "hey, you paid our inflated premium for XBL, but we don't have to honor the promotion despite the fact that WE didn't send YOU the information needed to claim it , and there's nothing you can do about any of it, so *** you". Completely unacceptable, and I gather I'm not the only one who this has happened to. I urge anyone who is in this situation to kick up as big of a stink as they can about it, and spread the word to anyone who is considering getting an XBOX that they can expect this kid of treatment from Microsoft, and they should go with a PS3 or Wii instead, which is what I intend to do.
