My account was just permanently suspended

My account was just permanently suspended. I started a match with my level 10 friend who just started playing the game. We queued normal blind pick. I was first in the lobby to call jungle. The Thamn Kench, Amumu, and Fiddle all took smite and proceeded to jungle. I went to start my red, and they followed me. So instead i went to invade the blue. They all 3 followed me. I was able to smite the blue, but on way to next camp the Tham Kench ate me and spit me out. I was not going to waste my time with 4 man jungle...3 of which following me around all game. So i went back to base and told my buddy to just wait and let the other team end as opposed to playing a 1 hour long match with 4 man jungle. This obviously mad me mad so I said a few things to the 3 jungle trolls. I reported all 3 after the game. Then when queuing for the next match my account was permanently suspended. I guess I could have just got leave buster and left the game, but wanted to hope for a quick end to this match so I could play again with my buddy. Im not trying to make excuses, but with no warning, chat bans, or anything...and based on the circumstances of 4 man jungle...i believe permanent suspension is harsh. Can anything be done about this Riot? Thanks.
