Got leaverbuster for starting a remake

So i was in a ranked game and when it started my premade realised he forgot smite so he was a good sport and went afk so we could all remake. We waited for the 3 minute mark and I wrote on the chat /remake and we all accepted the remake all normal so far.But when i got to the after game statistcs i got leaverbuster the game counted as a lost and i lost 20 lp or 17 a value inbetween. I was wondering if it was possible to remove the leaverbuster and get me my lp back if possible. thank you for your time and have a nice day.
