25 game chat ban

I was given a 25 game chat restriction after I afked the loading screen and didn't notice I had smite while playing support. I had to fix my daughter lunch and chose to do so after locking in my champ. Well I come back to being pinged constantly, and flamed with stuff like "nami you dumb F***". it was 45 seconds into the game mind you, haven't missed anything. I calmly explain the situation with my child. My adc replies with your kid should be dead with a parent who takes smite, then proceeds to stand in lane and not cs, claiming im the one inting. by the time the enemy adc had 100 cs my adc had 36 and was 0-7. anyways the game goes on he tells me I should be castrated and continues insulting me, calling me a snowflake and dumb f*** and I report it at the end, and ill admit I got carried away in the flame but I never cursed or used anything other than pointing out his gameplay. I received a chat ban for this game.
