Claims that you'll win a free vacation cruise for taking a 'green' survey. After agreeing to take the 'short 3-question' survey on green energy the questions centered around solar panels, solar panels to power electric cars, and if solar power should replace fossil fuel. To all 3 questions, I answered 'NO', then was congratulated for winning.
The next phase of the scam was to get your permission for the cruise line to contact you. Again, I answered 'NO'. The nice computer then thanked me and promptly disconnected.
Wouldn't it actually be nice if they didn't call again, but something tells me these folks are sinister and will make my phone ring again in the near future.
