Above is the email confirmation that I got from the Xbox Live Diamond Card People on the 30th of December. I'm sure we call all attest that much more than 6-8 weeks has passed since that time. I have recieved no card. If I go to the webiste I get an error stating that my Gamertag has not been registered. If I try to re-register it tells me that I can not register my Gamertag because it has already been registered. Long story short: I called them and they told me to call back later in the week to see if anything had changed. She didn't even ask what my gamertag was. I hate this world. If she'd had an Indian accent I would have hung myself.
