cant play matchmaking!!!!

Sooooo… I use my main account LF HyFeariuM to play reach… or at least I used to before one day I went to matchmaking lobby and says cannot connect to server and my rank and everything is gone. So I thought this was a temporary thing and thought something was wrong with the servers so im like whatever I can wait. Its been over a month and I STILL cant play matchmaking and honestly it’s kinda -Yoink!- me off.
I tried everything and still cant play matchmaking

  • I restarted my router many times
  • Made a new account CallMeHyFeariuM to try to play on another account
  • SWITCHED xbox’s and tried playing
    and nothing has worked and im guessing that im ip banned or something because its not my connection because i can play any other game except for reach and i switched xbox’s and profiles and still cant play. I don’t know why i would get ip banned, i haven’t done anything wrong and i just want to be able to play matchmaking again. I have posted the same exact post on the forums 2 weeks ago and 343 replied “your account is fine” and I have waited and still cant play and getting a little bit frustrated so SOMEONE FROM 343 PLEASE HELP ME WITH THIS PROBLEM!!
