Chat Restricted???

Hi, I recently got chat restricted in my last game. I understood I was a bit heated, but a duo that was in my previous game purposely banned my champ, purposely inted in that game, and then troll reported me. I tried my best that game and was the only one who went positive. My mid laner, and the adc, who were the duo, purposely int, flame me, and troll report me, and I get chat restricted?? Ok league, I see how it is.
