A player just called me trash

I found out after this game I was 1/2/25 as thresh. After the game a blitzcrank who is platinum V added me. I said yes? And he started to trash talk me about how bad I am and he called me trash for no

reason. I reported him caused I was in the post game (luckily).

I'm not gonna name the person cause it is name and shame

Edit 1: He was againist (remove) and (remove)

Edit 2: I remove the name cause name and shaming.
