Hi guys, can you help me please.

I took this bet in sbo. Uruguay to win all group games @5
Ok, Uruguay won all games.
But sbo is paying me only a part of this bet, because they are telling me that Croatia and Belguim got to win all their groups matches too. So they applies dead heat rule.
I think this is totally wrong. Because my bet, never considered the other groups matches. My bet was only Uruguay to win all their groups games, nothing more.
If I had to bet uruguay to get the most points in the first stage. Rule would be right, because 3 teams with 9 points. But this is not the case.
My bet not consider the other groups.
What do you think guys. Am I wrong? Or sbo is making a mistake.
Please your help.
