I'm being banned for junk reports, and I can't do anything.

I've been recently banned from ranked for junk reports. I know that I have no proof, but it's impossible that I'm banned for bad behavior. IMPOSSIBLE. I can't get banned for bad behavior because I'm not having bad behavior for months. I know the code. But I still get the "you've been reported" message in almost every game. FOR NO REASON.

Now I'm sure that I'm banned for junk reports, and nobody cares. I've just played my first draft game to play ranked again. I was playing as Alistar support witha Varus adc, and we lost the lane to a Twitch and a Veigar. And Varus starts to insult me and asking everyone to report me. Then he goes mid forcing fizz to come bot, and at this point of the game everyone's threating each other with reports. I muted Varus and didn't answer him back. But now I've been reported by Varus and Fizz for losing a game. In the first penitentiary game. I'm not going to go throught this hell again. No thanks.

I want a revision in my case, because I swear that this is 100% a mistake. I bet my account that it's been a mistake or I've been banned by junk reports (wich theorically the system should filter automatically).
