Ranked Gamplay

My friend and I, our summoner names are TwoChangz(me), and jimmysausagee(my friend), were in a ranked game, in champion select, a troll picked gangplank jungle, purposely, then, in game, proceeded to run it down mid and feed up to i believe 23 kills to the enemy team. I do not find it to be fair, nor just, to allow something like this to affect mine, and my friends in game rank, I would like to have our teams LP refunded, the player who inted, banned, and the enemy team can keep the LP, I do not know if my request is possible or will even be seen, however, I feel that it is extremely unfair, due to the fact that no matter what anyone in the game did, or didn't do, our game play was hindered, and caused us to lose LP that we worked hard to gain.
