low priority queue

See, yestarday i left a game because i had to go for higher powers (i know that i get a low priority queue for this). I get a 20 min timer and i start to wait. the timer ends and i can start a game. here is where the problem started. every time i start a new game a get this timer back. later i noticed that when my game has ended that i get a message in the right of my window that i have gona afk. this is ofcourse not true because i played the game untill the end. its verry anoying, and just trying to play. someone anny ideas where this come from?
