Who called from 5713640379

I don't answer unknown callers and though I get up early any telemarketer or charity calling at 8:30 on a Saturday morning would get a "no" and a warning from me.

Many calls from this # even at 8am, call blocker working good

Received a call from 571-364-0379. Asked for me by name. My response was met by silence before I hung up. Creepy.

Man calls up angry, screaming at me, have told him not to call several times.  Won't leave me alone.

Calls, asks for me, then does not say a word
