Game never ended

I won a game, i skipped stats b/c they were taking so long. when i looked at my LP it didn't move. i looked at match history, game didn't exist. so right now im just like "wtf" to myself. I qeue up for another ranked game and all of a sudden while im picking my champion the screen (force) changes over to the stats from the game that didn't count. So i'm really confused at this point i was about to choose a champ and i coudln't. Then i start to hear the champ select timer coutndown in the background. It actually forced me to dodge, I lost 3 LP(the game ended up counting after it did that). this was not my only issue tonight. 3 times something happened in game where me and a majority of my team and even possibly the enemy team got disconnected and caused the game to get ruined. I wasn't too mad about the disconnects that happened to alot of my games but this whole forced dodge thing really got on my nerves. It'd be nice if i could get the LP back lol . . .
