WHMCS service cancelled can not restore the invoice

[malin]

I use the WHMCS system, I have a service for customer use.

The customer can cancel the service.

But there is a question to me(admin).

If customer canceled the service careless, I can transfer the service to him again, but the invoice will not calculate any more, it do not recover.

>Cancellation Request Notice  
A cancellation request exists for this item and so it will not be invoiced when due

(the cancellation request button for customer)

Quote

If a Cancellation Request has been submitted by your client and they later change their mind, it is quick and easy to void their cancellation request. Simply navigate to Clients > Cancellation Requests, locate the cancellation you wish to remove, and then click the red X next to the request to remove it. This will stop the cancellation from processing automatically. You'll need to make sure to mark any invoices that were cancelled as "Unpaid" to prevent billing errors.

as long as the service hasn't been terminated yet, you can "uncancel" the cancellation.
