Dynasty Internastional Associates Inc. are impossible to Travel with!

In January 2001, my place of employment recieved notification of "Great Corporate Rates" for Florida vacations and a Bahamas Cruise. I was planning on taking my family to Florida for spring break so I jumped on the opportunity to get a Great Deal. Soon as I recieved the package I immediately tried to set travel dates, none were available, well the rates were good for a year and I could supposedly get an extension or transfer the package to another party if I didn't get to use it so I went ahead and set it aside for a few months. I tried again to set dates for the fall. At that time all the phone numbers had been changed and voice messages were at the new listings. I have left several messages, tried to fax them and tried to visit thier website. No actual persons seem to be available at any time! I have contacted my credit card company to see if they have any addresses or phone numbers and no luck ther either. Over $400.00 was charged to my credit card and I have been paying interest since January. I want my money back! Any suggestions? The salesperson I spoke was a female with a foriegn dialech and reassured me that they ahd been in business for 14 years and were a very reputable company.
