Received a completely unfair 14-day ban for 1 game of chat

Just received a 14 day insta-ban (was in que for next game when i received it) for the following chat in the game below. I was the jungler Yes it is the only game that was listed. I'm not claiming to be a saint but come on Riot this is just plain stupid. Of course you can't read the back and forth from the game but it should be clear that I was not simply raging and being toxic to everyone. Read the chat below and decide for yourself if this is a fair punishment. What is particularly funny is the last lines when it is clear now that nobody read the chat before i received my ban.
