I get chat banned but my flaming team gets away with it?

I think the honor system is fundamentally flawed. Last season I was honor 5 and after one game at end of season I got heated and asked a teammate to stop feeding in a less than optimal way I get reported and chat restricted resetting me from most honorable to not even able to receive honor. That's a bit harsh oh and no rewards. Then this season rolls around and after an entire season of receiving probably hundreds of honors I only make it to level 2 tier 2. Felt like to me I was receiving honor at a slowed rate and still being punished!?! On top of all this one of my most recent game I playing normal draft nothing special and wanted to play Xerath support, really doesn't seem to unusual I hovered it and everything no one speak up. I lock it and my bot lane teammate flames me before the game even starts. The continually flames me throughout the game after making extremely simple mistake dying 6 times in a row and feeding the enemy Jhin. But she continues to talk in chat flaming me and turning the entire team against me although I'm not the problem here and I was quite for a majority of the game, I ask her to stop chatting and play the game, and no it was in the nicest manner but that was all. After this I get chat banned again with no warning. You have a real way of punishing players riot not only with your lousy tracking of what honor actually means to a player to your unnecessary punishment of the honorable and totally relaxed position of toxicity. But hey whatever the more people who quit because of your oversight the better I'm really sick of it.
