Lost a game becuse a player didn't connect and remake was never offered

I lost 16 LP because a player never connected and the system never offered to remake. I even used the command at 3 min in expecting it to work. We never got 'a summoner had disconnected' or ' a summoner has reconnected' messages. They were simply never there. What is wrong with the remake system? If they connected only 1% or for a millisecond does that make a false flag and disable the remake command? Can't you make your system more robust by say, checking if they also have 0 CS and have bought 0 items? How can I get my LP refunded?
