Lost LP for a win

I was queued with a team of 5, and right before the game ended my wife and I had our internet shut off. My team was ending when it happened, and we won.

Then it comes back on and not only did we not gain any LP for our win with our team, we lost LP as if it was a loss.

26min game set up to win easily. I had my ADC friend super fed, and he carried as I set him up to do.

Please award our LP back plus what we should have gained based on our standard LP/win average.

Here is the game in question where it bugged and caused us to not gain, plus lose LP for a winning game: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2328042497/38171955?tab=overview
