Can we all call Loretta Sanchez, our congress lady and ask her team investigate this entity? Loretta has been rather responsive to me on other issues. Maybe we can have some government intervention on something that REALLY bothers the citizens and not all the b s they send our way.

Brian, thanks for your post here; sorry about your predicament.  My parents' number also got spoofed to the point they were afraid to answer the phone.  I don't know how you could catch the creep doing this, but even though your phone company won't help, you can report this to the FCC & local police, & maybe try this sort of greeting on your ans. machine before picking up: "This number has been spoofed; If you have received a call from this number and do not recognize it, we regret your inconvenience, but we did not call you. Government agencies are aware of and trying to resolve this situation. Otherwise, please leave your name & number if you wish to speak to me and I will return your call."
    Yeah, I know this sounds simplistic or even corny, but this DID eventually work for my parents & the calls gradually stopped.  I'm sure this would make lots of folk calmer and see you've been honest and the victim here, so the calls to you might soon stop as well.  Good luck!

just received a call from a b****th that said her father is a licensed contractor.
Maybe his call is spoofed but maybe not the voice on the vm recorder sounds similar.
Next time they call I set up an appointment and the poor [***] that shows up

just calls no one speaks

Had right name for household, clearly not simple robo dial
