Someone from this number called my mother-in-law.  Demanded my phone number and address, when she refused the lady told her it was a legal matter and extremely important she give this information to her but she still refused and the lady hung up.  My mother in law called my husband and he called this number back.  The lady on the other end did not identify herself, who she (might) work for, and just demanded his phone number and address.  She told him IF he would give this information to her she would pull up his file and tell him what it was about.  He refused and she told him it was in his best interest to give him this info.  He told no that if this was legit she would already have info and would not be so shady on telling what it's about.  What is this?  Is it legit and if so don't they have to tell you who it is and what it's about?  And NOT be rude, nasty, and demanding.  Anyone else ever get this kinda call?
