I received this unwanted call today, 17 May 2013, at around 9:50 AM, from NY.
The man insists that he is calling because you have taken an online survey that connects you with employment opportunities, even if you tell him that you do not remember any such survey.
If you ask him for this supposed survey's website address, he will hang up on you.
Please hang up on the number and block it from your phones. Beware of such scams.
