Termination will take place at the end of the current billing cycle if the request is received previous to 24 hours before the end of the current billing cycle. Cancellation requests received within 24 hours of the end of the billing cycle will be effective at the end of the following billing cycle. For example, if you wish to cancel your subscription starting August 1, your cancellation must be made no later than 11:59 p.m. on July 30.
Cancellation of a month-to-month subscription takes place at the end of the month in which you cancel. Cancellation of a yearly subscription takes place at the end of the year in which you cancel. You will continue to receive service for the remainder of your billing cycle (month or year).
No credits will be issued for any cancellations made within the current billing cycle (month or year).
