its_not_physics

To anyone who can help, My GT is "its not physics" and I was banned from Matchmaking in Reach for the second time in as many weeks. I don't know why. I am not quitting, and I can hardly say I'm earning a truckload of credits. Whenever the match loads up, I am dropped and put into either the lobby screen or put into my own matchmaking to choose a game for myself. If that happens, I am spit back out to the lobby anyways. This keeps happening until I am eventually banned. It's like Im losing the connection and being dropped. Its frustrating. Like I said, I never quit games unless I have to. What can I do? ***After ten min ban*** I am still 'quitting'/ auto-quit/dropped. It has gotten to the point where I don't even touch the controller... Help!
