Today on my first placements in EU West

So tonight i decided that i'd do 1 of my placements without my communities permission,and since my computer was starting to get a bit better i felt like this would be a winnable match. Wrong on that part,cause i was against a gankplank that swap with their orianna,and i picked teemo. I inted this match,and my teammates where gold last season,and i was bronze,and i also saw a diamond ranked player. To think that knowing you have two gold,and a diamond ranked player in your team,and the critic the living shit out of me. So when we lost the match,the kassadin decides to be a ass and spill the salt on the wound to even make me feel bad. "intentional feeding,griefing". That's not even close to what i was doing,i was talking to them which i shouldn't do so since all they do is just troll me the entire match about my strategy i had planned to counter gankplank. And after the match i find out that i'm not the only one who has been having it bad,i told them i'd screenshot everything and i intend for them to just know that i got them. The next time you see my username,know that it's a 50/50 chance we win if you just shut up about my picks,and have fun. Cause i want to have fun climbing up the ladder with a crappy PC that i believe riot told me to get looked at. I got a Windows 8 program running on a Windows 10,and i get only 14 fps at 145ms. So i thought it'd be easy since i was facing orianna top lane, but they swapped. i told them that i'd switch with kassadin,and they replied with "you must be on something',and continues to let the orianna push mid lane.here's the pictures of their profiles so that i'm not lieing about being a 1 trick,and then for having as the same streak of wins/loses as me.
