I received this call on my work number. The caller ID listed only the number and was an automated "survey" promising cruise tickets to the Bahamas if I answered. I tried pressing zero to get to an attendant so I could have my number removed from their list, but the computer just said my "answer" indicated I didn't qualify for their prize and hung up. When I attempted a call to the number on the ID, I received a Verizon message that the number had either been changed or disconnected. A google search only concluded that the number was a cellphone in Tuscaloosa, Alabama.
