Caller ID says Chiropractors S.  Called and left no message.  Other sites report that it is a free cruise scam but can't verify that since no message was left.  Plan to block,

called and left no message. caller id says unassigned number. scam.

Caller ID said Chiropractic S. When I answered it was a recorded  survey from Green something saying if I answered a few questions I would get a free cruise. I stayed quiet after a few repeats of the same thing the recording said we will remove your name immediately. Yeah, I've heard that before.
