Game Keeps disconnecting (PC) and games not counting

Every time I play a game, it disconnects me randomly at random times of the game and the whole game doesn't count. I've played about 10-15 games out of which only 2-4 were counted as they didn't disconnect. I expect compensation for this as it's a big waste of time and effort and none of it is going towards my champs qualifications or objectives. It started right after the new patch/update.
