4. I got that one too. The guy even gave me a phone number when I asked if I could "call him back."
I checked the number on the internet and found several complaints about scam attempts. Then I called the number and told them I had reported them to the authorities and hung up.
I also called the fraud dept of my credit card to report this call even tho I had not given the caller any cc number. I wanted them to know that this one is "out there." They hadn't heard of it but were glad I called to alert them.
