Looking for a rioter

almost before 3 weeks i got suspended for 14 days because i joined a game (Odyssey) mode.. the rest was a premade of 4.. they wanted to do mission with 2 augments.. told them from pick screen i don't need that quest but the one with 3 augments.. so, we joined the game.. they could surrender easily (cause i would 100% press yes if they ff) and go onto the next one or find a 5th premade so they can do whatever quests they wanted to do.. the fact is i was clear to them from pick screen.. but what did they do? they prefered right after we joined the game start all flaming at me, wishing me cancers (note that i've lost 3 members from that sickness) & slaughter to my family.. that triggered me in a very bad way.. so we were 2 groups.. one of a solo guy and another of 4 premades flaming at eatch other.. someone will say that you could mute them.. ofc i could.. like i did with countless other kids like them.. maybe it just happened to wake up in a bad mood? the fact i've lost members cause of that sickness triggered me badly that day.. i accepted my punishment and waited patiently for the suspend to go off.. before couple of minutes i joined a ranked game with 2 duos.. camille at top with our jungler zac, vayne adc with our mid irelia.. enemy jungler kayen literally got his sleeping bag at bot and dived us all the time.. camille started flaming at us nonstop (zac also but this game didn't talk too much so he is not much of an issue), so i told her "shut your mouth garbage.. this is why i hate duos" and then asked on /all chat from enemies to report camille for flame.. ps: kayen before we write on /all chat praised me and vayne.. he said to our team to honor us, because we deserve it.. maybe cause we stayed cool and didn't flame.. also said that we are unlucky to have those teammates.. so i wonder if it's fair to get perma banned on a account, which i've spend so much time & money on it since season 2, because i told to a nonstop flamer "shut up garbage"?
