Wow, I've been "selected" for a "free" cruise to the Bahamas! Oh happy day! Except it's all a scam.
Google: free cruise to the Bahamas scam
The fake "survey" they mention exists only to take advantage of a loophole in the Do-Not-Call Registry; an exemption for survey calls. Too bad for them there have been successful prosecutions against scammers who tried to work the fake survey angle. Their turn will come.
In the meantime, don't be a sucker for this swindle.
Called. I did not answer because called almost 6PM. I do not answer unknown numbers but did not left me a voicemail message. That means it's not important to me to even worth calling back.
I answered in a different language than I normally use, and they hung up on me. (P.S. I did not answer in English) Because I thought the number, especially the area code looked suspicious and unknown. Called back, found "survey now over," pressed 9 to be "removed from future calls." Yeah. Sure!
