Are you crazy? Don't EVER EVER respond with any type of personal information to anyone who asks over the phone. Not a birthday, not an email address, NOTHING. Good grief ... then people wonder how their identities are stolen. All it takes is a few pertinent bits of information gathered here and there and, voila! You're the target chosen. Why on earth would you ever supply a random caller with any information at all? Duh ...
I just got a call from this number and since I did just fill out a trusted survey online the other day I answered all his questions. He asked name bday and zip code and email, should I be worried at all? I don't believe that it was automated, I asked him a few questions and he answered them.
