Thank you to all who posted the valuable info on this site. Got a call from this number today. Didn't pick it up because I didn't recognize it. Now I know that I will never answer this call. Thanks!
This number has called me a couple of times over the past week, and today I finally answered. They say they're calling from some cruise company "on a recorded line" and ask if you can hear them okay. I recently heard about a scam where they call and record you saying "yes" by using some sort of "can you hear me" question. They then use the recording of you saying "yes" in various ways to scam you/claim you agreed to some sort of contract. Sounds like that's what's going on here. Be careful with this one, folks.
