i keep getting calls all day long from this No

I get this number all the time.  A message is never left.  Calls are from morning to 9 at night.  If you call back at some point you get a recorded message about if you know your party's extension or 1 to access the directory.  If you continue to stay on the line as it says you can, at some point pretty quickly it says goodbye.
