Accept/Decline game popup

Hello, When I queu for a game I can not accept / decline the game because it simply doesn't shows up and the time keeps running, when i cancel the queu it seemed that I lost 13lp for not accepting / declining the queu ( I tried it 2times) meanwhile I just couldn't and I got a wait time of 30min before I can requeu..? Can someone please help me with this bug. I really want to play.. Greetings, Im Steax
