You should do the same thing that I do about this. When you answer a telephone call from a robocaller, you are telling the computer that called you that your phone number is active and that you answer robocalls. Doing that just gets your name put on their sucker list, and crooks sell their sucker lists to other crooks!
P.S. – I am writing this because 2 days ago I got a voice mail message from “the awards committee” saying that I had “just won a free all-expense paid vacation to Bermuda, including the airfare.” The caller was a man. He spoke with an accent that sounded to me like he was from the British West Indies, but I’m not sure. He said that in order for me to claim my prize, I had to call him back within 24 hours with my credit card number and security code to “verify” my identity. The call came from the 234 Area Code. That’s the Area Code for Nigeria. I didn’t call him back because this didn’t smell entirely kosher to me. Several people have told me that I have a suspicious nature, and I think that’s true. Anyway, it’s been more than 24 hours since I got this message, so I guess I’ve lost my free Bermuda vacation.
