I C Sytems Possible Fraudalent Request for Information Internet

4/7/10: Received a call from IC Sytems/Miss Ward.  She asked for me by name and I confirmed that was who I was.  She then wanted me to verify my address.  I asked what the call was about.  She said it was a personal business matter and again asked to verify my address.  I again asked what the call was about and she had the same response.  I asked who IC System was and she did not answer, just again asked me to verify my address.  After several rounds of this back-and-forth, she said if I did not verify my address shed have to terminate the call.  I responded that as she had not said what the call was about, Id terminate the call.  I suspect we hung up at approximately the same time.
