Call no talk many times always, please investigate .

Disturbing calls

This number calls almost every day.  No one is there when you pick up.  I am elderly and could trip trying to get to a phone, only to find out that no one was there.  Please investigate.

I get two or three calls from this number everyday ad nobody's there. This is on my cellphone and I'm sick of it. If you call it back it says disconnected or no longer in service.
