So for example, let's say I buy $30 worth of Crysta (3,000 Crysta) via UltimatePay, with $14.95 on my account. After the 3,000 Crysta is paid for on the day make my second billing, I'll be left with 10 Crysta from the $29.90 I have paid. Will my account be automatically cancelled the moment I have 10 Crysta or will I have a grace period before the day I am billed again to buy more Crysta?
