Terminate all billing of an existing customer and lock the customer down unless otherwise un-cancelled. Canceling a customer also cancels subscriptions and purchases associated with that customer. Cancelling applies the same cancellationOption to the Subscriptions as was specified in the Customer Cancellation action. For example, "Full" will reverse the Customer the full value of each Subscription active on their account.
