Game didn't finish at load screen, got a leave

Hey there, I queued a ranked game, picked Braum during champ select, and got to the load screen. 1 person on each team never connected and I loaded to 100%. Their Leona loaded to 43% and stopped there. I spent 25 or so minutes waiting for the game to finish loading.

The load screen never changed from that state. After waiting quite a while, the load screen closed and brought up an end game screen. I was awarded a Leaver status and no LP, even though my team won. I would like the Leave removed please.
