Yes, calling from the USA. I called all the different numbers, including the USA access phone number. Yes, during 9AM - 5 PM Manila time. I also tried 9 - 5 Eastern Standard Time. Whenver I call, even when I call during the correct business hours, a recording states "Please call back during our regular business hours". It doesn't matter what day, what time, what number, I get that same recording. I also had a friend call on their phone multiple times and received the same results.
