If you search the phone number, you get Pacific Telecom. www.ptswa.com
Right on their website, they apologize and state that they are not responsible for the calls. They list the agencies to report the calls to along with websites. REPORT THE CALLS AND THEY WILL DO SOMETHING ABOUT IT!
Why would anyone answer calls unknown to them? You know its a computer dial and a telemarkerter and if u answer they will ALWAYS keep calling back, so just dont answer problem solved.
