I need help urgent

<p>I'm quite confused......i'm an international student and i registered for the dec 6 SAT subject test, but was absent on test day, so now i want to change my test date to january 24. I called customer service, but no one is there, and the comp says (call during business hours). I'm live in UAE, so according to eastern time....i shud call between now and 5AM(my time).</p>

<p>My question is.....if i call them on monday (cuz its christmas, and they may have a holiday) and transfer my date to jan, will they accept it....or tell me i'm too late to register? I can't miss this date....the deadline for online registration is 2morow(dec 26) its my last chance. If anyone knows that they don't accept it....then i'll register online and pay again...cuz i can't take a risk.....does anyone know which time is too late to transfer ur date to another if u were absent?</p>

<p>P.S International students dont have late registrations online.
THANKS TO ANYONE WHO REPLIES.....i'm REALLLY CONFUSED =/</p>
