Called me at my office. The guy gave me his name and kind of fumbled a bit, then started to ask me to verify personal info, starting with my year of birth. I asked him who he was, and he just gave me his name again. Then I asked him what company he was with, and all he said was "Account Control". So I hung up.  It sounded like he was in a call center, because I could hear other operators in the background. The number is based in Bakersfield CA.
