Multiple calls from this number in recent days.  Last night when I didn't answer they called right back as if it was a cell phone in my driveway that knew I was home and couldn't understand why I wouldn't answer.  They even started to leave a message the 2nd time but hung up instead.  To me hiding their name alone is reason I don't want to speak to these people in any way shape or form.

This number keeps calling and I dailed it back with no luck

Who keeps calling as private number?
