The "owner" of 657-297-4018 is a business. I'm on the "Do Not Call" list (each of my phones were listed separately), but it matters NOT to this business. They use Robo-Calling and, when I was called, were "selling" extended warranty's for your "less than ten years old vehicle with less that 150K miles. My "NEWEST" car in a '70 Datsun 510 with a bit over 350K on the clock! This makes it plain that the called numbers are randomly generated.
The Attorney General of California SHOULD be keeping tabs on ALL businesses in Calif, but especially "Phone Bank" and "Boiler Room" businesses. Violating the "Do Not Call" request is, as I understand, a Federal Offense!!
