These scammers use different names such as Crown Home Improvement, California Design Center, Clearview Home Improvements, Anaheim Home Center. Most of these don't even show up on a Google search. I suspect they are all the same group, since most of the numbers that they use all start with the same area code and prefix.
This same guy uses many numbers including spoofed numbers. he is pretty nasty and has a back handed answer for anything you can say. I bet he gets his laughs by reading our posts on this site. Big Jerk. I would call him something else but I will not have Tom or Huck thinking badly of me......I am now classifying his calls as "crank calls", not as sales because he is a lowlife.
