I was held hostage in a game with a toxic trio while we had a disconnect and I got wrongfully banned

I was just in a game where I played as Ezreal adc and I had a Zoe support who was disconnecting from the game, never loaded in.

This Zoe wasn't a problem though, the other 3 were. Kha called me a "fucking retard fucking n-----" and constantly told me to kill myself. But the other three on my team must've been in a group together because they all ganged up on me, calling me the n word, and then telling the enemy team that I was calling them the n word and since they had 3 people against my self they all believed them. All game they were calling me a n----- and a retard and telling me to kill myself and then playing victim in all chat. I was entirely helpess in this situation!!! So after the game the enemy Lucian adds me and says he is sorry for the game, and then I get banned. Is there anything I can do to repeal my ban as I was the victim in this game? Edit: I have never had a restriction on my account before. Edit: chat logs:https://docs.google.com/document/d/1EqlEst6_SOsKjYHcMQuquNv7T6-H63xjirb_uzMcuxk/edit?usp=sharing
