Got flamed the entire game for having a bad game.

So i was playing in d5 soloq just trying to climb, the usual. So about 10 mins into the game our Garen starts flaming me for "taxing" him when i took 2 cs and the rift herald.. So after this he procceeds with taking my red cus of the cs i took now i really dont mind about any of this but after the game my Jhin told me to kill myself about 4 times in the after chat. And the Garen decided to start flaming me aswell nothing serious, so after all of that is over he adds me and spams me too kill myself like 5 times and asks me "how are you gonna do it?" This game keeps on amazing me with the community. Now i'm really trying too improve my behaviour after a previous chat restriction but it's really hard too keep my cool when people like these are in my team. I have his name and everything and he blocked me before i got too screenshot the chat. Now i have no idea where to put this stuff but i'd love an update on if he will get banned or not.
