5 dnf's out of your last 20 games, 2 of those dnf's were one after the other.Didn't bother to go back any further because if you have a 3 day ban then that means you have quit on numerous occasions and you have had bans previously.And if you say they were all dissconnect's then there must be somthing seriously wrong with the connection at your end, i.e wreless instead of wired and port fowarding might help, hey maybe reset your router and perform a ping test and see what your packet loss is.Also when going into a game it states "Matchmaking rules apply" If you can't abide those rules then do not play the game, their game their rules simple as that.
