By choosing an auto-renewing payment plan, you have agreed to GMC's Terms for Sign Up. This procedure gives you continuous access to the product you have bought, without needing to worry about your account expiring.

If you don't wish to continue using GMC you need to cancel your subscription before the next payment date is due, in order to stop it from billing you again for another period.

It is not possible to get a refund if you do not cancel your subscription in time.
