What happens if a customer disables auto-renew on a domain after an invoice has already been created for it? (Enom)

Right now I have the automation set to generate a domain invoice 30 days prior to expiration, and automatically process the payment 15 days prior to expiration of the domain. I think it may happen that someone sees the invoice for the domain renewal 30 days prior to expiration, but then decides not to renew it, so they go into the settings and disable auto-renew for the domain. Will disabling auto-renew for a domain after the invoice has been created, stop the automatic payment from processing?

The invoice will be cancelled.
... in theory. It's not consistent at all. Especially if an admin disables automatic renewal.

The invoice is supposed to be cancelled but we've lost thousands in domain renewal fees because customer disabled the automatic renewal without the invoice being cancelled. In most cases, the client will ask for a refund because the didn't ask for the renewal.
It has been a problem for a long time.
