Who called from 4082142031

Finally banned them with my jcblock device, 4 recent calls with no previous history.

Air Duct Cleaning, again. They just don't understand what "DO NOT CALL" means.

Reporting them does NO good, if it did they would be out of business.

I have received multiple calls from other numbers using the same rip-off pitch.

I've given up reporting these scams so I just block them.

Called multiple times. Informed them that they were lying about having done my duct work.  Same voice keeps calling me back.

I got another call from 408-214-2031. He just said, 'hello, may I speak to mr rz'. And then he just hung up. He has done that again and again. His voice sounds like he's a caucasian guy. And looking at this list here, he repeats that frequently.

This number has gotten cell phone numbers and calls house, then cell, changes ID and repeats.  Have no idea what they want, no message left ever.
