I'm punished for being attacked?

Basically I want to know how wrong/right I am in this situation. Below is the support ticket I submitted to Riot, just because I don't want to try to re-explain what happened. I recently received a chat restriction because almost every other person in the game reported me because I lost lane. The entire game flamed at me, on both sides, said very offensive things and would not leave me alone. I should have muted them, but the things they said to me were setting me off, so I responded with aggression in return. I understand that I shouldn't have done that, but who can handle 9 other people being incredibly rude and maintain a cool head? If you want to punish me for trying to defend myself fine, but I refuse to play this game any longer if all those people get to walk away scott free after basically cyber bullying me through your video game. That kind of thing should not be allowed to happen. And I for sure should not be the only one punished, if punished at all. Again, I accept that I handled the situation incorrectly, but I was forced into that situation because the players in the game were intentionally aggravating me. If you review the chat logs, one player openly admitted to trying to make me angry and attempting to see if they could make my cry. I'm asking for a full review of that game, and even if my punishment isn't lifted I hope you'll consider punishing the people who caused the extremely toxic situation to begin with.
