412-347-0109 called me on November 5, 8, 11, 11, 16, &18, 2016. My caller-ID usually turns up a letter "V" with several numbers [not the telephone number on the caller-ID]. Tonight I called them back at 10:30 PM and got an automated message that they were closed. There was no mention made in this recorded message of their identity. And they had the audacity to ask me to leave my name and telephone number. What really freaks me out, is that I called Verizon customer service to ask about blocking these nuisance telephone callers. I successfully added their number to nine others on my Verizon block list and yet they got through to my caller ID. Perhaps Verizon takes a day or two to actually stop these tele-pests. (412) is an Allegheny County area code near Pittsburgh in Western Pennsylvania. I sure hope that Verizon's caller block system isn't a placebo.
