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

Dear Referee Jerry Maclas
Did you sleep good last night after the vallayball match between Japan & Thailand.

Last night the whole World who love sport and watched this match felt very surprised and question why you judged and purnished Thai team as unfair judgment. When the system not work and they informed and requested for some change but you play neglected. What happen to your judgment? Unacceptable!!

I myself understand very well for every kind of sport we may Win or Loss up to the performance of each match. I can understand and accepted the result of the match between Thai & Italy & Netheland, we lost. But last night match was not fair and you done the judgment unprofessional.

FIVB committee please investigate and public annoucement the conclusion of this judgment. We hope to get your kind consideration thank you.
