These creeps call me at my home, work and cell numbers. When I answer, they hang up. They don't seem to be selling anything. They seem to exist purely for harassment.
This phone number is Power Home Remodeling Group, formerly Power Windows and Siding. They're a home improvement contractor that uses door to door sales tactics to pick up customers. Some guy came to my place from them over a year ago and knocked on my door. I only answered because I thought it might be a package delivery. Oops. Then they throw you a big sales pitch. I just wanted him to go away. I actually did give them my phone number just so he'd shut up and go away, but I have never answered their calls. (They must have called me four times a day at first. But they haven't called since until now.) I tried calling back to tell them to remove me from their database completely, but I got sick of waiting for someone to pick up while they played all their idiotic "did you know" pitches.
P.S. I just tried once more and got through quickly. I told them as soon as they picked up to remove all of my info from their database. The guy did not argue or try to pitch me any further. Of course, when he looked up my record, it sounded like the only thing they wrote down correctly was my phone number. The address was completely wrong--both the number and the street name were misspelled. Anyway he said it might take up to 24 hours for the do not call list to sync with the dialers, but after that I shouldn't get any more calls from them.
