Random server disconect. Give me my lp back!

So I was playing a ranked game today at 23:10 and out of nowhere both me (mid laner), my supp and the enemy top laner disconect. We were not even wining but we were comebacking and it was extremely tilting to know we just lost when we came back. It was not our internet, computer or whatever you might think. It was purely the server and I know it happened to a lot of other people cuz I had to wait on a 3 min queue to get back to the game. I was one game away from promos and so was my supp and while we would prob loose the game anyways it's just not fair to loose like this. I m specially tilted thinking about the people who were actually wining and might have lost because of this. I understand that this might happen but I think the game most definetly should not count! Just give the lp to those who won but dont take it away from who lost as this is plain unfair and makes people turn away from your game. My friend is already saying he is gonna uninstall, after all the shit he got on his past games to just loose a step away from promos cuz of the game servers is too much. Sincerely, a random player
