This is UNFAIR

Riot after a streak of victories matches me NO with pro players, with very bad players, really bad 0/7 0/10, etc, this is not a coincidence, it happened a few weeks ago also after a winning streak, if Riot is managing my games, I do not feel like I'm playing anymore, I know that after a bad game, my winning streak will return and then another one of defeats, this is not fair, this is SCAM I feel cheated and I want to know what the hell is happening, this is not legal, this is infamous and I want to know WHY this is happening, this is a scam, I demand an ANSWER NOW, if I have to lose I want to lose on my own, if I have to win, same, this is SCAM, it is illegal, to alter by some algorithm my games is to lose and win according to what Riot wants, not me
