8 Losses because of noob mates

I played 8 ranked games and i lost every one of them. My cs is good, I dyied not more than 3 times and won my lane(mid) every single time. After 5 min my top or botlane or both dyied more than 3 times and this game is lost. In 8 games i had 3 akfs which was 0|10|0 laningphase. Is this bad luck or something else? I never tilt btw but this makes me really angry. ( I played the 8 games not in a row)
