Hi, I work for Carnival Cruise Line as a customer service rep. Please be warned. These calls are not coming from our cruise line or any other that I am aware. It is not the practice of any cruise line to telemarket it's Guests. A few months ago I received several calls from people trying to confirm their cruises they purchased over the phone from such calls. Needless to say there were no such cruises purchased. Please get as much information as you can and report them to your state consumer services bureau. I can assure you Carnival Cruise Line has already started an investigation into this matter.
Have been getting this call a few times at work (Metro Vancouver area landline). I received the same fog-horn message 3 years ago on my cell phone (Okanagan area) and actually did the survey (gave false answers) after they called me everyday for a few weeks.
At the end of the survey they ask for you to enter your credit card number to verify your age. I didn't, so it put me through to a real person (what a b**** too!)
I asked who the company was, how they got my number, etc. She wouldn't give me any direct answers and if memory serves me correctly she swore at me and hung up on me.
