Banned For Dumb Reason.

First off, Im starting to regret paying 60$ for this game.
I left a match that WAS NOT what i selected.
Selected BTB got FFAS, I left game cause I suck at swat.
Selected BTB again. Got it this time. Finish the first round having fun, suddenly Connection to game lost.
I look over at the game list.“One or more player in your lobby is banned.” Im the only one in the party.
Go to menu. Got banned for “Leaving too many games.” Wtf?
So i wana know how i can get unbanned for this stupid systems hickup.

There’s a ban thread here:
