The best direction I can give you is to write to CLIA (Cruise Lines International Association) at this address... http://www.cruiseforward.org/contact   They may not be able to help you directly but may be able to lead you in the next direction. I would also write a hand written letter to Carnival Cruise Lines at the address given here... http://www.carnival.com/about-carnival/about-us/address.aspx .  Have you attempted to contact Carnival at all? Did you book directly with them or through an agent? If through an agent, have them make some calls on your behalf as well. Good luck :)
