Called about 30 minutes ago. Diverted by a service I subscribe to that intercepts robo-dialed calls (rhymes with SoNoHobo). Callback w/my ID blocked gave me the recorded "The survey you were called for has now finished," which from past experience is most likely related to "You have won a free cruise" if you answer a ridiculously simple question. As with time shares, I suspect they make their money once you give them your credit card number.
Called on my cell -- left no message -- tried to call number back within 2 minutes, and and got the 'survey closed' voicemail -- S C A M ! - sure sign --- now that I see that it is a scam I WILL BLOCK IT --
