Scam.  I am not sure if this is a robo call or not.  I have gotten calls from numbers that look familiar to me and they all start out with a human voice which says "Are you there, I was adjusting my headset." As soon as you say anything...a human sounding voice goes into a script about them calling because I've stayed at their resorts..blah blah blah.  No matter what you say,  the voice keeps going at the same pace,  no pauses.   This is obviously a scam.
