Please give a legit explanation why team Thailand lost two points and does not allow substitutions s

#1: -  

  It's obviously see the game that Japan did foul by falling down on the white line, referee didn't notice and Thailand is not allowed to challenge and prove themself. Not only TH didn't get the deserved point for that game, they have right to ask for challenge but also referee gave 1 point to Japan. I think it's not fair.

Thailand didn't do aggressive manner to referee they just did what everyone in the world surely suspect, that it is acceptable and reasonable. Is it reasonable that  the referee gave 2 points to Japan and red card to TH?

And also the substitutuion system issue. Is it good enough standard to use andacceptable? Why TH cannot change the suitable player to be same standard as Japan. This is the world standard competition. It's not supposed to be like this.

The result is not fair!! We would like to denounce the standard of this program. Please arrange new competition with more fair game.
