Who called from 6156100506

AGC local number call before we come out today to serve you. Give some one notice they are coming, That's some kind of stupid....
maybe they think every one is as dumb as them. Robo dialing. All robo dialing should have a unalterable serial number like a MAC address and you could track.

one ring then hang up - 2 days in a row
no message
never heard of who the other callers on other report a number services say it is...
