Ultimative team rivals

I'm playing now like 2-3 days max online -rivals and I had like 4-5 games (3 in a row) that after I won the match, the game load Infinite, after I push advance and even if I wait 10+ minutes nothing happen and if I close the game and open it I got a report for leaving the match(DNF) + I don't get my earned win... That's frustrates me because I'm getting penaltyzed with no reason ea to often, all games end normally with a final whistle from the Referee. I won twice right now (around 7:10 time in greece)and after the final blow... Just loading screen.... And a DC penalty Message(DNF)... Over and over again... Makes the online game unplayable....shouldn't happen at a 80€ game.... (My internet connection is rock solid!)
