Looking at your cert files in our system, your cert was activated on Friday, May 17, 2013 11:29:45 AM and should expire on Monday, May 20, 2013 11:29:45 AM. This time is in GMT +8, which if converted to EST should put your time of activation at Thursday May 16, 10:29 PM. As your order was also placed on May the 17th, and you opened a support thread regarding some issue with the service at 12 noon on Friday (GMT +8), I'm not sure where there's a discrepancy in subscription time, looks like you had your full 3 days?
You can check the same thing for yourself, by visiting the BolehVPN\cfg\OpenVPN folder and opening up the .crt file with your BolehVPN username on it.
