Orbitz Worldwide Inc No real price assurance, Internet

Apparently price assurance is not available on any package vacations.  I booked my vacation with Orbitz less than a month ago and now see that the price of the vacation has dropped by approximately $500.  Orbitz will do nothing to assist with a price adjustment.  When I called them and waited on hold for a total of 20 minutes, they insisted that in fact the price of the vacation had gone up since I booked it.  I pointed out that I was looking at the same vacation online on their site and it in fact was almost $500 less.  Then they explained that there was nothing they could do for me.  I work in the hotel industry and I know that reservations are changed and rebooked all the time.  They are not very customer service oriented.  They should point out that price assurance is only on individually booked items and BUYER BEWARE FOR PACKAGE VACATIONS.  In this economy I would think that some customer appreciation and the fact that you would be willing to spend any money in this economy would get you more than "I am sorry there is nothing I can do, have a nice evening."
