I have a 20 minute low priority queue that does not leave

I got a low priority queue that hasnt went away for about 30+ games. The only game that i can recall leaving was about 40+ games back but why did i recieve it so much later? I have tried to put in a support ticket but whenever I sumbit the ticket, i check the My Tickets tab but my ticket is not there but only the ones that I have put in in past uses of the support system.
