False Reporting

I was recently reported after a ranked game but not for flaming or anything toxic like that, it was for playing me main.... Teemo. Yes, yes I do realize people hate this champion but really? Constantly in ranked matches I'm flamed and cussed at to high oblivion for choosing him. Not even a minute in the game and they are telling me crap, and now i can't communicate with my teammates just because of who I main. Why does Riot allow this or just let it happen without acknowledging all the toxic crap that happens in this game?
