2. Billing Cycle - All HiTech Creations members are billed in advance. Upon subscribing after the initial two week trial period, you will automatically be billed for one (1) month fee. You will be billed on the same date for each subsequent month of membership.
According to the "Support" document. Same date you subscribed it seems.
But, I'd contact HT for this answer, I doubt any account specific detail will be answered here.
