I've talked to Xbox support about this issue and the last Agent I talked to told me to put the issue on the forums. So that's why I'm making this post.
People that participated in the Xbox Dashboard Beta Testing have gotten a message of "LIVE" telling them that there's a reward reserved for participating in the Beta Testing. The message also contains a link to a website for further instructions. This website is currently down. I contacted Xbox support 2 times. The first Agent told me that the Server Engineers said that the website would be back up in 24 hours and if that wasn't the case that I could get a special link to redeem my reward. As I said before the website is still down, and so I contacted Xbox Support again. The second Agent I talked to told me that I had to post my issue on the forums and that the website would be back up ASAP.
Thank you for taking the time to read this post.
