Lose streaks and bad/non-existant matchmaking

Hey guys, I am right now in a horrible losing streak and I wonder if this game even has a matchmaking.

Every player has a certain skill. And this is (wrongfully) determined by the MMR I guess. I am on two accounts (have a bunch of alternatives) Silver I. So I am pretty sure I am Silver I. Fine. But when I keep losing and losing, my MMR is sinking, right? Below my actual skill. Eventually on Bronze V level. But for some reason, the free fall does not stop. It does not matter what I do or try, the enemy just knows the game, my trash does not. Do not come with "Dunning Kruger" or "negativity bias", because pure numbers in their history and gameplay does not lie.

Last game I had a 4-premade of which one guy, Warwick, did not even buy an item and started right away with a 1,100 gold item. The enemy however, do not have this sort of useless trash "mates". They are normal or good players, their premade are actually a threat. It's pure sabotage, but RIOT likes offender protection, so you are there to smile it away while wasting time. Going AFK comes up with this ridiculous "negative experience" message and penalty (what if the "team" "mates" are the reason why I left in the first place)?

As SoloQ, I am screwed over by this crap. I keep losing no matter what, either because my premade are terrible and/or the enemy just works together. My trash does not even speak English or does it over Skype. How am I supposed to get anywhere?

So I keep losing and losing and I am probably Bronze V MMR-wise and still lose. Then I am allowed to win a 25/0/6 game and the next 4 games the same trash noob mates again. Is there any sort of matchmaking? And if yes, it can't work.

Is this the "Dynamic Queue"? Am I screwed over because nobody of my guys play this crap game because of this anymore and moved over to, ugh, Blizzard (for reasons I can understand now). Right now I am at 19 games and 14 losses. And the majority is due to noob junglers that die at camps, trash premades, disconnecters etc.

RIOT logs everything, when you fart they know it, when turrets go down. But logging losses due to AFK (by a non-premade) and then putting potential AFKs on the enemy side for compensation? Nope.

How is this game supposed to be competitive when rolling dice would work any better? I am here since July of 2010. Back then, the game worked. But the high school dropouts employed for RIOT got hands on the code and now we have this wonky nonsense (MMR) by too many people (x10) together with premade handicaps (uncalculable) and then call it a "match making" when some guy brings his trash friend into the game, dragging me/us down.

Someone at RIOT who is in charge of this pile of shit is not right in his head.
