Got DC on a game that had already ended and despite winning i got a lost.

This is one of the most frustating things that had ever happening to me. I just won a really hard match 4x1, the judged already ended the match, i had won it, but before i got the reward i suddenly got a DC for some reason, and i got a penality for a non finished match and a loss in WL. The exactly same thing happened last week on a 9x2 macth. It is just discussing, 15minutes of my life wasted on a pointless game. Im not realy good at the game so each victory to me is important, things like this is frustating and makes me just want to quit the game. EA should at least compute the result of the match just in the moment the judged calls it to prevent a thing like this to happened.
