Please fix your game

So I was queued up for Aram and the queue popped. I clicked accept one time. It put me into champ select but the match accept/decline was still on the screen. The game was also completely frozen. I had to exit out of the game completely with task manager because I could not press the X. Once I got back into the game I had a leave buster of 14 minutes. One of my friends also said the same thing happened to him. Riot please fix your client because we don't want to be punished and waste our time for your mistakes. So please take more time on your client instead of using all the time on reworking and new champions.
