So if you are getting flamed and leave you get chat banned?

Hey, I'm not always the nicest person in my league games, and I'm not proud of it. That being said, I got chat banned for a reason I find stupid. I am a teemo support main. I understand many of you hate the champ, but I enjoy it and carry myself to gold playing it and that is enough for me. Because I main an unconventional pick I get flamed a lot.

This particular game, I was playing teemo support and had a Draven bot that I was getting fed. I was like 3/0/1 and he was 1/1/2 or something. But he would b often, cuz he got hit by skillshots a lot. While he was b, the wave was pushed to our tower, so I was last hitting the minions. He flamed at me for farming the minions, so I called him an idiot. Yes that was not nice. Game continues, he keeps flaming me whenever he does something wrong. He gets stuck in lux root and its my fault, etc. Eventually I say that I don't care to play with a toxic adc, especially when I am carrying him in lane. Another teammate jumps in on the flame teemo wagon, and nobody says anything in my defense, so I afk. Again, not the best reaction. I told them if anyone could say a single nice thing I would get right back in the game, nobody did.

Not saying I deserve an award, but really I get banned? Why should I have to help carry a team of two jerks and two people who wont even say a single kind word? Full chat:
