These pricks, "Cleaners" call my emergency line that is unlisted and on the DNC List. I blame San Bruno Cable for briefly not having my phone on Wednesday when I transferred from AT&T to my local cable company. Don't bother to call me back because you only verify that your phone is a number to be called back. Don't waste your time with that do not call list registry as they have proven to be a waste of time. My only suggestion is to save the phone numbers on a piece of paper and bring them to your local representative during an election year and ask them about improved legislation protecting privacy or imposing new laws enforcing phone privacy laws
Yes, they called me too. It is advertising a vent cleaning service. They disguise their phone number because the phone call is illegal if you are on the national Do Not Call list.
