These are the same A..H...s that used the number 972-737-8071 to call me over 150 times from June 2016 to Dec. 2016. Apparently they retired that number and are now using 972-598-9035 to call me 29 times since January 2017. I wish some smart computer guru could trace their location so they could be prosecuted.
I think it is the same as 8071, 8075, and 9035. They are the most frequent repeat callers now. When the harsh light of publicity revealed who was using the 8075 number for harassing the public as a roofer and their sketchy background, they suddenly quit using the 8075 number in Dec 2016. Now it is 8071 and 9035.
A harassment complaint can be filled with Verizon or ATT or etc. Log down the date and time of the caller and when you have 20 or so contact the phone company about filing a formal harassment complaint. Not answering, not leaving message and not removing you from their caller list makes them harassment calls, not sales calls.
1-972-598-9035 has been calling 3 times per day for the past month. Our well known call blocking service has flagged this as robo or a telemarketer call.
