Getting booted from ranked games

So today I logged in to play some ranked and on 4 separate occasions i was in champ select and mid bans/pick in my chat it displays everyone leaving the room. From here there is no timer on the bans/picks. the game does not start. I am forced to close the client. I then proceed to log in again only to have to wait 30 minutes to play a game due to jumping Que and on top of this I lose LP every time. Anyone else get this at all.
