I just received a call from the above number.  She said that the call was being recorded for security purposes and sounded professional.  Next thing she wants the last 4 numbers of my SS.  I asked who she was she gave me her name but would not say what the call was regarding until I gave the info she asked for.  I said I am not comfortable giving out my SS.  she said we already have it we just need the last 4 to identify you.  I gave her the last 4.  Then she wanted my address.  I said no, not until you tell me what this is about.  I gave street name and she said that she had to have number too.  I refused. I phoned them back and she answered.  No company name.  I asked who I called and she was very vague would not give out info.
