matchmaking is bugged

something is seriously wrong with your match making. i'm currently plat 3 20 lp. and it's been 2week i have either only win for 14 game, then only lost game for 15 game. no matter how well i do when in loosing streak i get some idiot teammate, and when i win i either carry it super hard or my mate do.

http://matchhistory.euw.leagueoflegends.com/en/#match-history/EUW1/229328935 look at that ! i demolish the teemo in lane and roam for kill? lost, my botlane is garbage. i get overfed as fiora and get like 2 X triple kill while being 1v3 ? lost i do the perfect early game start on xin zhao jungle? my mid is trolling . i DESTROY the tryndamere in lane , roam, help my team, but opps, botlane is useless. WHAT CAN I DO ? and previous week i had the match history FILLED with win, with everytime score like 10/0, 12/3 . something is rly wrong, what is the probability of loosing 10 game out of 11 ? and it happens EVERYTIME

i'm lauching a game right now but i'm pretty sure someone is gonna troll/feed his ass. how can i enjoy this game when i loose 10 game in a row even tho i play good?
