My account has been baned but I dont think there is enough reason to do this

MY account has been baned, because i was feeding on enemy on a rank game. The reason was because my team support Morg wanted to invide enemy red buff, and i said no because i was playing Ekko and Ekko is not like Lee Sin or Udyr, those jg champions are strong at early game, but Ekko is not strong at early game, so I just wanted to farm my jg, and when i get stronger i might try invide enemy jg area. my support said, "I will fuck you Ekko." i was thinking oh who cares i just do my jobs that's all, if u want get feed then i will gank bot at level 3. but i didnt say that because gromp coming. and guess what? Morg take the last hit on gromp and i didnt get money also i can't level up to level 2. Ekko is not tankly champion, after Morg took gromp i wont be above to take blue buff on my own, but bot lane wont be help me anymore, i will be underlevel after few mins. This Morg made only one small mistakes but so bad for our team, its Butterfly Effect, but he didn't think about how bad this will do to for our team and for me, because when i m under level i wont be above to gank any of our lanes, because jg player are usually under level than lane player, when they get level 6 jg player are usually level 5, after Morg did that to me, I will be level 4 when my teamate level 6. Morg didn't care about that, he is so selfish and individualism, he made our chance to win down low to 30% (was 50% on the beginning), he has no collaboration at all. I think a player like him is who really need to ban forever, not me. I always try hard to win when i play, but this player made only one small mistakes, he didn't think what result he will get after this. I hope you guys can do the right decision: unblock my account, and ban that player for a while(maybe like few days i think.) I have been play this game for 4 years but this was the worst player i ever seen. PS: I know my English grammar is bad, because English is not my first language, so thanks for reading.
