The posters so far are essentially correct: no policy has been broken
here. Its entirely up to the ISP to decide how (or even if) they
manage or delegate RDNS. If you can, you should fine another provider.
If your provider is a monopoly like the Bells or cable companies,
there may be a local venue in which you can file an actionable
complaint. At the very least you can try a complaint at the better
business bureau.

Two additional thoughts:

ARIN's preference to refer to the ISP as a "Local Internet Registry"
is a problem here. It implies that the ISP has a duty to competently
manage all of the delegated resources but at least for the RDNS that's
simply not true. If we're not going to require reasonable management
of the resources, we shouldn't be referring to them as LIRs.

Who's the ISP? I'd like to call up their marketing manager and suggest
that their customers have been hurt and reputation damaged by their
mismanagement of the RDNS. A little ridicule placed in the right ear
can go a long way towards correcting undesirable behavior.
