Got a call from this number. The caller left no voice message.

Received a call from this number, but did not leave a message

I have received multiple phone calls from the phone number 704-764-6014, they never leave a voice mail, they will never talk when I pick the phone up and when I try calling back it just beeps.  I have gotten well over 20 calls from this same number.

Called 3 days in a row , answered once ,nobody was there,other time left no message

THey don't leave messages,  called it back and get a rapid busy signal.
