Fuck is wrong with your matchmaking system riot? Like its utter garbage what the fuck?

Hello,fellow summoners? ( that was the best intro i could come up with) If you've been having issues with the matchmaking ( ranked ) please upvote this so any rioter can get to see that there's defiantly something funky going up with the freaking ranked system matchmaking. 1-: i am a platinum 4 EUNE (Meka Elfky) 2-:IN EVERY single game i play i get gold5s and no im not playing badly you can check my account on op.gg. 3-:The you get placed based on your rank and your mmr can come suck me dry till im dead because im platinum4 platinum4 mmr getting between 24-27 per win and im placed with fucking goldies (trash g5-g4) and nearly every game they're autisming around and none of them has my mmr nor fucking rank i'd rarely get platinums nowadays. 4-:Fix the ranked matchmaking its abusing my mental health. 5-:now if any of these goldies were playing as i was playing i would've fucking had low mmr but i don't,my mmr is climbing so fucking slow like 10 mmr per win or less,and i've been playing warwick jungle yesterday went 9/2 and my mmr went from 1800-1824 which is fucking weird like 11 wins and i get 28 mmr? is this is a fucking joke? Can anyone respond and tell me whats wrong? i issued a ticket to the support but they just said nothing rather than '' you get people who has the same skill'' ( none is even fucking platinum ) The rank ladder of P4 has fucking 10 or less players i don't care if queue time is long i don't want fucking golds in my games PS:GUESS WHO JUST GOT A FUCKING SILVER 2 AS HE WAS WRITING THE THREAD AND HAS TO WAIT 15 MINUTES NOW BECAUSE OF THE DODGE?
