Received call for third day in a row, despite that I informed them previously that they had a wrong number.  When I said,"You have a wrong number, stop calling me," the caller responded in a nasty tone, "What?"  I then asked if he was calling from California, because I don't know anyone from California.  Caller then hung up.

Caller called two days in a row.  Second time, he asked for, "Kathy," which is not my name.
