This is a persistent scammer.  They called me twice in one day.  Once at 10:37 am on 03/02/2017 and the 2nd time at 12:59 pm on 03/02/2017.  I do not have voice mail set up just so I do not have to listen to it.  They were not on my contact list so I did not answer.  I have a very long list of contacts so if they are not on my list I usually don't answer.
