Suspended account

My account was banned for saying "k" three different times with nothing in between. What I mean is, I said the letter "k" in response to my team raging at me 3 different times. Riot claims that this is a racist and that I'm not allowed to say "kkk" which I didn't say. I said "k" three different times in three different statements. So the first time this happened I messaged them thinking this was a big mistake. It's Riot though and they never ever have made a mistake and all their decisions are final. So I let it go. That was the first time which was a chat restriction. So just to test the waters and actually see if that was really what happened because I was still dumbfounded it ever happened. I said "k" three different times in a different game in-response to toxic comments on my gameplay. This time I get a 14-day suspension. I am officially done with this game. Now I see why their trash game is dying. They refuse to ban anyone actually being a bully and pick on someone who isn't. This game has become the worst part of a joke. Their's no balance, 20/120+ champs are viable and if you don't pick 1/20 viable champs you're a troll and get ragged at all game. Wonder why they have lost 30% of their player-base in the past 6 months... it remains a mystery. Anyways GG riot, go ahead and perma ban my account as I won't be returning along with the other 10 people I ran this game with on the daily. We are hopping on the Fortnite band wagon and not looking back at this piece of shit.
