30 Minute Queue in Ranked

So let me get this straight, if i purposely dodge a game for very good reasons, I have to then wait a while before I can play another game?

I recently got into a ranked game where I specifically said I wanted to support. No one said anything so I assumed I would get it, plus I was 3rd pick so it wasn't like I would be waiting a long time. First guy on my team picks. Then two people on the other team pick. Then it's my turn and that of the 2nd guy. The 2nd guy doesn't click anything so I click Karma. He then picks Thresh. I assumed he was going support so I click Diana. He clicks Annie. I click Karma again and he clicks Thresh again. The timer was clicking so I pick Diana and right before the timer runs out, the 2nd guy picks Leblanc. I asked him what he was doing and he said going mid. I told him I was originally going to go support, to which he said he wasn't paying attention. I close down League and get a 3 minute wait before I can play another ranked game. No problem.

I get into another ranked game where one guy said he would feed if he didn't get to be ADC. He said he was a plat smurf and when he was called out on it, he said he would now feed. I wasn't having any of it so I don't pick a champ when it's my turn. I get hit with a 4 minute wait queue.

I just tried getting into a game where the guy banning on my team bans Fiddlesticks, Singed, and Fiora after we asked for Darius or Garen or Vayne. He said his bans were "on point". I had already mentioned I wanted to play Support, to which I received no response for or against, so I assumed I was going to get it. 1st guy picks Bard with Ghost and Flash. I asked him where he was going. No response. Yeah he could have gone Support but with zero communication, I wasn't 100% sure so I dodged again. Now I have to wait 30 minutes before I can play a ranked game.

I'm Bronze 4. I started out in Bronze 5 but I crawled out of the mud and into more mud to get there. My goal is to get to Gold anything before this season ends so I get that sweet Sivir skin. But at this rate, I highly doubt I'll get it. Why should I be punished for people's inability to communicate with their team or their desire to ruin the game for me/my team? I want to win, I want to get to Gold, I want that Sivir skin. I'm not a toxic person, I'm not an AFKer, or a feeder. I know how to play the game and I think I do a fairly good job playing Karma support. I always play a game to win. So, with that outlook for this game and my ability to play it, why am I getting punished for trying to save the little LP I have and that of my team's? (Which I should I also mention is strange. I was at 0 points. I won a game, received 22 points but instead my score went up to 19. Ummm, what?)

I'm down right pissed off right now. I don't think I deserve this sort of punishment, let alone this sort of treatment. But what am I to do?
