they done it again

i don't how people do this, but in normals. when you call a lane before someone else, they don't select a champ. causing them to get kicked out champ select queue and disbanding the game. but then they join another game INSTANTLY without waiting 5 minutes? wtf?!?! how??? rito please fix this glitch.. i have no idea how they do it, but i seen this done a lot.
