I got Permabanned for my team throwing?

I got banned for player toxicity, when the worst thing I said was "shut your mouth" I was heavily tilting because this Evelyn decided to jungle with me, even after I told her no, I had already called jungle, yet she still locked her. Then the entire enemy team reported me for unsportsmanship behavior because I was telling the enemy team to report her. They still got negative about it, and in the end they mostly cursed me out, and called me a little bitch saying "its a game, chill out" with the Evelyn saying "I don't care" which is ridiculous, and I end up getting banned for unsportsmanship conduct? ARE YOU KIDDING?
