Ya the same thing happened to me. I was console banned from matchmaking last Monday. It sent me a message and said the ban was for one week. It is now Tuesday 8 days later. I called Microsoft to get a support line for bungie and they said the best thing to do is communication through the forums. This is clearly a problem, all we ever hear is "just wait out the ban" well I've waited it out and I'm still banned. This is where the bungie moderators need to step in and let us know what is going on.
