Received call and returned it.  Recording stated "heavy volume of calls etc.; press named key on keypad for removal from their list.  Did not press for removal, just waited for a person to come online.  Person came in and stated their name and a company or something of both which were not understandable.  Was able to find it is a  solicitation for investors in real estate etc.  Asked me if I had received their mailing.  I replied I have not although I haven't checked my mail for the past  two weeks as I've been out of town.  No professionalism was apparent.  I responded "I'm not interested in investments and also am registered on the National Do Not Call registry."  Ask that they remove me from their list as I don't want to be contacted.
