CID showed number only.  I listened to the whole thing as I was trying to ascertain whether it was a live caller or a computer with programmed responses.  The call is essentially the counterpart to the scam faxes you get from "The HR Department" about vacation packages for 6 days/5 nights in Punta Cana, all included, even airfare for $99, plus the first 150 employees to respond get a bonus 3 day/2 night trip to Disneyland!  I believe it was a computer and they are becoming more sophisticated (unfortunately).  It believed I said yes when it asked if I was at least 21 years old, though I said nothing, and hung up when I did not respond to it asking if I still had a valid debit/credit card.
