I've actually had the same thing happen to me. I was down to 2,096 from a 4k queue and then back up to 4k with another character. I got lucky, I had a 2002 error and got back in fast enough to log into my main. It gave me my spot in the Queue back. I was about to go off, since the day before I spent over four hours in queue and kept getting kicked back to the end due to DCing and not being able to get back into the game.
