Once again rcvd a call from this company  " Dept of ACS" this time the name caller left was Dexter Brown ph(347) 289-3120.  I had told this caller I could take a msg for the person he was looking for and this caller said" I have called serveral thousand times and I don't think you are giving msg"  I told this call I have and I have no control if this person calls back.  I also questioned why this caller has called and left diffrent names and I even gave names he has left behind the caller said that was other people in his office yet he had just told me he had called " several thousand times".  I just told this person I would take another msg.  Names this caller had used: Dexter Brown, Officer Joe, Joe Brown, Gerald, Dexter Frog, Gilbert.
