That's my favorite. I'd say that gives you free reign to call every
hour on the hour until it's done, asking for an update. If you call at
4:30 PM and it's not done, time to ask for a manager, and then the VP,
and then the owner.

Bravo Sierra. That would break all sorts of things if that were true
for lots of their customers.
Of course, since you probably know who at least three of their
larger(ish) customers are, you could find their IP's they use via
forward-DNS in a flash, and then you could apply the tool below to see
what THEIR reverses say -- I bet they're delegated!

dig -x <ip address>

Anyone there claim to "know Unix"? They should be pickled in their own
juices if they can't do simple DNS. (And yes, reverse delegation is
SIMPLE.)
I heartily recommend "DNS & BIND" from O'Reiley & Associates as their
first step to cluefulness. Next stop, RFC 2317, which was published in
March of 1998... probably time to get on with reading it.
Sorry to rant but come on... I could do a few digs from here and send
them the exact lines to put in their reverse zone file if they'd like
help with the syntax.
If they're supremely retarded and need visual aids, www.miceandmen.com
makes some Windows-based check tools and management tools that are
actually quite useful too. There's even
https://secure.menandmice.com/mmForms/dnsx_test_now.jsp which is kinda
nifty if you're willing to part with some personal information.
