Bad Client made me go into Low Priority Queue

Riot I am not happy at all with your client right now I've played this game since season 3 and never had this problem with the older client but now all of a sudden when I finish champion select the game doesn't even load but on the client the game will say the game is still in progress. This happened once yesterday and it made me lose one promotional game, I tried again and it worked fine but just now it did the same exact thing which ended up making the game go into remake, naming me a leaver and then leaverbuster putting me in low priority queue if this keeps happening i'm going to get banned for an obvious bug from Riot. This is not even fair my internet is fine, my computer isn't slow and nothing is blocking league (I checked prior to this post being made) I'm very unhappy and frustrated that something like this has happened, it shouldn't have happened I haven't left a game since I was a new player in League. Please Riot fix this client and its issues.

TL;DR Client won't let me load into game and got me put into low priority queue
