0 Ganks

Hi. In ranked i had twisted fate in mid lane feeding so its not problem when you do lose lane but that dude keep pushing lane after 2 loses and got killed all the time it was 2 deaths in first 3 min already so thing is he blamed me for not ganking him. flamed all game on me. so the thing is why ppl like that dont get ban ? i did told him to not push play safe. that didnt work so at the end of 6 min enemy team had 4 kills mid lane so i wen for kills top and bot because there was no point going mid anymore. so thing is we lost and thats ok but why such toxic players are alowed to play ranked ? he flamed all game on me caling me broze and ect i played best i could and got positve score but still feed was too strong . i was jax in jung. sory for bad english :(
