I got a second call on my business phone at the same time.
Wouldn't tell me their name. Wanted to know my name. I said you won't tell me yours I won't tell you mine. I have them blocked now.
Receive daily calls - do not wish to pick up. My cell phone number is on the do not call list.
This number calls mulitple times per day, never leaving a message. When I call the number back I get a message saying the number is temporarily unavailable.
