Solo/Duo Ranked Queque so missed up

iam a plat v i just played my placements matches 2w/8L Why?ill tell you why coz maybe i played with unranked jinx last season and a total beginner...and i was the supp..she didnt know how to use ult nor farm not dodge or side steps and my opponent was blitz and she kept standing on his hock over and over and the next game i had unranked beginner sivir who actually wanted to play yasuo..now everyone wondering if he took sivir adc why he wanted to yasuo?actually his declared role was jungle..so matches after matches had ulimate trollers/afkers/haters rito said that she made the queque better and made a better enviroment but thats obv a lie now iam silver V from Plat V thanks rito for backing up your old players.
