Been getting calls from 864-059 for several days and various 864-215 #'s all day today. Think they are related. When I let the call go to VM, no message was left. Usually, with #'s I don't recognize, I pickup and immediately hangup. Answering validates that this is a working #. They get the idea soon enough. BTW, my landline/mobile are AT&T. Also, my understanding that the do not call list (I'm there since day one) only works with toll free #'s (800,855,866, etc) unless you report a reg # (864-215-1202 for ex) but there's no guarentee the calls will stop. They call from various #'s they bought. I'm in SC. (Really, you answer and it says goodbye? What a way to run a business!)
