Another scammer, calling about resorts or some such nonsense.

I answered this call even though I didn't recognize the number, thinking it was a work contact I'd just given my number to calling me (on my CELL PHONE) about a project we were working on.  After saying "Hello" there was the tell-tale silence of a telemarketer, but I still thought it was my work contact.  I said "Hello" again, and after a moment a woman came on the phone with me and said "sorry" and something about her headset not being on right.  Then she said I had stayed at their resort in the past and.....and I hung up and blocked the call right away.   I do travel a fair amount, but the fact that they didn't ID their company right away, or even ask for me by name, were two more red flags.  I tried to call the number back from my work landline on the off chance I was wrong, and shockingly it said the survey I was calling about had already expired.

Definitely scammers.
