Disabling a customer with this method might not be the most ideal
solution, mainly due to TTL periods. If the customer neglects to pay,
and you disable their DNS, not only do you have to wait for caches to
expire around the world before there domain is "truely" disabled,
when/if the customer does finally pay, you have to wait for the changes
to propagate again.
You might want to look in to simply redirecting there site to a canned
"This domain is disabled" page using Apache itself, that way its instant
on/off, and the customer, or the customer customers actually get some
feedback and not just a "page cannot be found" error.
