Hi there, Caution187! If you are part of the Premier/VIP program, which allows you to pay your bill 14 days after the due date, and you pay after the 14 days of grace period then those 14 days are charged to you from the next payment, making your billing cycle 14 days shorter. You can find details in this website http://boost.co/2mmiaxk. If you've never been on the premier program, feel free to send us a private message so we may take a closer look into your account.
Since your account was interrupted when the payment was made, the due date changes to that day. However, since you paid after the 14 days of grace period, 14 days are charged from your billing cycle. Therefore, since the 14 days passed and the account was interrupted, after the payment is done you get half a billing cycle.
