Ok. I answered. It's a chipper sounding woman who starts off by saying "HI!" after that pause that tells you it's a robocall. Then she laughs and says she's got to adjust her headset, then she tells you she's calling because you stayed at 'one of their' resorts and so has this FANTASTIC offer for a multi-day stay at another of 'their resorts', meals included!! "All you need to do is answer a few questions before I turn you over to a representative..." So I asked what resort I stayed at and managed to make that last sentence repeat twice before they hung up on me. Sad!
As always, the lesson is, unless you recognize the number, don't bother answering. Annoying!
