WHY you do this to me, RIOT!

So I have a chat restriction, because everybody on my team and opponents reported me cause they said I trolled that game, all because of the reason, this jax turret dives for a kill but before he can escape he died and i was right there, and my team blames me cause I didn't use my heal to save him. My response, "Why would I do that, he probably knew the consequence of turret diving and I am not wasting a heal on him, due to my reason that im not playing support role, so why should I save him, when i am ADC I Only think about myself, and if they cant except that then they should shut UP. But did they No, they called me troll the entire game, and told opponents to report me, also I was afk for 5 mins due to personal reasons, and they said troll and wouldn't stop picking on me, Later in the game when we were about to lose, this velkoz pretends he was afk but he wasn't cause he was never disconnected till 10 mins later, so he was purposely not helping the team. I tell everyone to report him because he was also afk, but No one does expect me...NOT FAIR!. I had a legit reason to leave for 5 mins, and he didn't, he was the real troll if u ask me. We win the game cause I help out and push the lanes and since I was jhin I was excellent in team fights, and due to this reason we won, while this velkoz sits there at base, AND I GET REPORTED!. They kept on calling me troll to the extent at which I started saying, " OMG UR SO GOOD, UR LIKE FAKER!", then " P.S. that was SARCASM". This was negative attitude, I will admit it, BUT EVERY PERSON Has their limit to how much they can tolerate, u can't tell me to ignore them, its not in my characteristic and it shouldn't be, I deserve justice. IF I HAVE A CHAT RESTRICTION, EVERYONE ON MY TEAM SHOULD ALSO!.
