“Renew” means to continue with the subscription after the present expiry date.
“Cancel” means to cancel the present subscription. No more payments will be taken, but the subscription will run until the expiry date.
“Abandon” means to stop your subscription immediately, deleting your account and private details. Be careful not to select this option if you only wish to cancel your subscription, as your account will deactivate immediately and any subscription payments will not be recoverable.
