My queue pops, I hit accept, it says "error game not found" and takes me out of queue.

I wait 20 minutes to be able to queue because the leaver buster system. So I wait 20 minutes to be able to queue, then another few minutes for the queue to pop, the queue pops and it says something like "game was not found." Instead of just putting me back into queue it makes me have to wait another 20+ minutes. So now I have to wait 40+ minutes to play one game. I got leaver buster because I recently left a game that my team was getting completely stomped and was basically impossible to win but my team didn't want to surrender and save time so I just left. The game ended less than 3 minutes after I left because it doesn't say "leaver" in my match history. (it takes 3 minutes of leaving a game that ends to be marked as leaver). So riot wants me to stick around for another minute or two and if I don't I have to wait 40 minutes to play another game? What a great game 10/10. I LOVE LEAGUE OF LEGENDS.
