WHY DID I GET BANNED???

I was playing big team when the tv hdmi was accidentally pulled out. I took about 5 minutes (as the cables behind the tv are a mess and how tight the space is to even get to the cable) and when i finally got the game back up, i was banned. WHY? I was playing a social gametype as well, big team slayer? What the hell?! Can i atleast see why I was banned or for how long? Why am I spending so much money and time on a game that bans me for having a life outside of it? What the hell?!
