I won a map, but the game said no

I played Call of christmas map, I've 2 control points and held it for 24 hours. That was a requirement for victory. The game gave me 50 000 gold, so I though everything was fine. But soon, one of the map players texted me that other player was declared as a winner. I checked the map again and here's what I've seen. As you all see on the picture, game gave me winner's reward _ 50 000 gold, but declared USA as a winner. USA has never taken any control points but he is declared as a winner somehow. now I miss 1 solo victory on my profile. That is not fair. I spent 3 nights to win that map. who is responsible for that problem?

here is a game ID: 4169318
