Vacation cruise scam. The call starts off with a fake survey. Asks if you use a debit card or credit card to buy groceries....they ask if you own your own home etc.  All of this is just to see if you own a credit card or not.

I answered the call and completed the survey because I get a kick out of wasting their time. And the longer I keep them on the phone, the less chance they have of ripping-off someone else.
