Didn't get lp for winning but instead loss some

WHAT THE FUCK! IS YOUR PROBLEM LEAGUE. I WON LANE I WENT 10/2 THEN MY GAME DISCONNECTED FOR LIKE 5 MIN AND I GET LEAVER BUSTER AND LOST LP EVEN AFTER WINNING THE DAMN FUCKING GAME WHEN I RECONNECTED 7 min before ending the game MYSELF. This is unacceptable fix ur game. if only their was some way for you guys to fucking give me the LP I deserved. the game lasted 39 FUCKING minutes and I get a leaver and no lp. you wasted my time to reconnect and carry my team after reconnecting to lose LP in the end. User : How To Climb bring back old league rank system if this shit is gonna happen to all my other lp lanes
