Someone called to ask to speak to me and wife answered.  They asked to speak to me by name and she said that I was at work.  They then stated, "at ??????" and named my place of employment.  She said yes, and they said ok, bye.  They wouldn't leave a message and they never called me at work.  I called this number back asked for the name of the person that appeared on the Caller ID.  He verified that it was his name, but they had never called me and spoke to anyone...???  How could this be?  Are they using a fake name with a disposable cell phone to try and phish for info.  How did they know my name and place of work
