Jason,
My advice is to check your contract for details of what the publisher
agreed to do in regard to promotion.  If there is something useful there
bring it to their attention immediately in writing.  Keep notes of your
phone calls etc to the publisher in regard to the matter and perhaps
seek some basic legal advice.
For future reference - amend your next contract with a publisher before
signing, discuss details of promotion in full and if not included within
the contract itself, write out an attachment in which all dates for
obligations of both parties are made clear and all discussed details of
promotion are set out.  Have the publisher co-sign it.  These little
steps help a lot and give you some back up should anything go wrong
later.
Publishers want books and like any contract - never sign their first
offering to you.  Bargain and get the best deal.
You may even want to have a meeting with your publisher and go over some
of these details even at this stage and see if you can come to some firm
arrangement to cover your concerns.  Have the details from the meeting
written up and get them signed.
I learned by experience.  Also are you a member of a Writers Guild? If
you just cannot deal with the publisher they may be able to intervene on
your behalf or offer some further assistance.
If the book shows potential of selling a good quantity you may be able
to find another publisher to co-release through.
Hope some of this helps you.
