I was just reported for being toxic in my last match...

I was being harassed by a team of a team of at least 3 people, blatantly feeding, spam pinging me.. I had to mute one of them of them, just a bad experience. They all started in post game about how toxic I was (barely said anything once I realized they were completely trolling as a group) and I got a pop up that I had been reported... something I've never seen before. It may simply be a warning and in the grand scheme of things it probably doesn't matter, but I'm angry that now I look like the bad guy. Is there any recourse I have to have some kind of disciplinary action against them, purely on principle?
