This number calls my phone 2 or 3 times per day---from 8am until 8:30 pn.
Ther is never anyone on the line.  When you call right back they tell you
that they missed your call and wll call later.  I wish they would drop
my number from their list.  I have other things to do beside answering
the phone call that has no one on the other end.  They should be more
considerate of households.
