Calling from multiple numbers , pre recorded call, claims to be from Green Study Surveys, and if you just answer three questions, you win an all-expenses paid trip to the Bahamas for two.  Sends you to the so called travel agency (I identified) who keeps you on hold and never comes online, while another recording plays telling you to bring your sunscreen and camera, and have your credit card ready for the $59 fee you have to pay for the "free" trip.  This is the second such call in two days, all from 218 area code.
