DYNASTY INTERNATIONAL ASSO. INC. DO they exist ????

I received a cruise & stay package as a gift from my brother on occation of my marridge. This package says it's valid for 18 months and needs 45 days advance notice. I tried to call these people at DYNASTY INTERNATIONAL ASSO. INC to fix the date on their 1 800 no but there is no one to take the call. You can only leave voice message and no one seems to bother returning it. Looks like $149.00 each for two people is RIPPED OFF. I really feel sorry for this rip-off since my wife was eagerly looking forward to it, and I kept promising here once I get time off we will fo on this cruise.

The package comes with the letter signed by E. BURNS (Director of Operations). and address is :
Dynasty International Associates Inc.
4235 Dale Blvd.
Dale City, VA 22193
Ph: 703 730 6492, Fax : 703 878-9140
Web : dynastyinc.com
There are couple of other phone nos : 18004308353, and 18772976840 (This one is disconnected without forwarding number).

I don't know what to do at this stage ? where to file claim ? etc. Any advice ???
