A duo troll

So i was hovering over Riven and the hecarim and jhin started to flame me calling me names and when the ban went over to jhin he banned riven, She's the only toplaner that I know how to play well a new champion who i don't know how to play. And in the game they started to act all nice like they never did anything, they told the enemy team that i was just a tyler 1 troll and the enemy belived it, I was being flamed and no one belived my story not even the other 2 guys on the team, I felt useless like I could not do anything they kept on harrasing me until my wifi went out because of a storm and I just got back on my computer.
