how do i get out off low queue

Play the amount of games the punishment is for

What if you were never actually AFK and it still gives you low queue? Check my match history.. never afk but still get this low queue

Nobody can remove the timers but you. You have to wait through the timers before each game before you can play. Once you play through a certain amount of games with the timers you'll go back to games without timers again.

Play moar games. Eventually you'll be out of low priority queue. This is what we call a "Good Thing™".
