Do you refund the money on a cancelled subscription?
The initial free period is setup to allow for trying out the service without any payment. A user can cancel subscription anytime avoiding incurring further cost. When cancelling a yearly subscription, all future charges associated with your subscription will be cancelled, however your cancellation will become effective at the end of your current billing period. You will not receive a refund but rather your subscriber benefits will continue until the end of the current subscription period.
