I do not think I deserve to lost LP in this game

The lee messed his own gank and path up, flame jax then rage quit, jax messed up himself too then seeing lee rage quit so he raged quited too. turns into 3V5 and I was down in bot lane kinda winning. HOW IS THIS MAKING ME LOSE 21 LP? I DO NOT THINK I DESERVE TO LOSE ANY. and yes I did reported both of them, if this is not like a year of ban then plz give me my LPs back.
