Asked for me by name, but refused to identify themselves, claimed it was a "marketing survey" -- which of course means they expect me to provide details and information on my own time for no pay -- most legitimate companies pay for whatever research or demographics they require to conduct business.  The fact that they would not reveal their name without confirming mine proves they're not worth dealing with.  When you get a call like this, ask the caller if they're being paid -- if they say "yes" then ask them how much they're going to pay you!

I GOT A CALL FROM THIS NUMBER TWICE AT WORK ON THE SAME DAY.  I DID A REVERSE LOOK UP AND THE NUMBER COMES FROM ONTARIO CANADA.  I DO NOT KNOW ANY ONE THERE.
