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

Thailand woman volleyball team, 6 players v.s. Jap team 6 players + 2 referees + 1 jap assistant referee, who control the asking for substution and challenge via tablet. Supposing the Thaailand press the tablet asking for substution or challenge but the Jap assistant referee doesn't press her/his tablet to accept or ignore this. Of course thiis signal will not show on the tablet of the 1st. referee. The Thai 's staff coach have told the referees that there is a problem with the tablet and this system. The Referees refuse and ignore this problem but give 2 red cards and 2 points to the Jap team instead. He, the Maxican referee, think that Thailand's staff coach trying ti delay the game. I dare to say that the Jap using the whole system for cheating this match.

  This is a shameless match for The FIVB, the referees, Mr. Wanabe , a head coach of Jap woman volleyballs tesm. This cheating victory will follow you till the olympic in Rio and forever, Jap.
