4 man group harrasing one person

hi all, i usually dont do this but this one went to far. i just played with a premade team of 4, who banned the campion i wanned to play, picked my lane and made every one in the game go against me, i have never felt wors of harasment and group presure EVER in league. when i wrote to the enemy team to maybe make them see my part of the story, they took the premade 4s side. the only think i kept thinking was if this continiue to happend then i don`t wanna play league annymore, i hope some one can take a look into this.

i hope someone can find them and make shure they dont do this again.
