Actually picked up phone and answered this number despite CID listing as 'Unknown.'  Middle aged lady identified herself as from Southern California Telephone and Energy Co.  I googled it as we spoke and it IS apparently a legit company.  She said she 'works with' Verizon to lower my bill which numbers and particulars she quoted to me!  So they have some access to Verizon.  Told her I was on DNC List.  Then I called the number on the company website (800-840-6673) and spoke with a real person from Cust Service.  He sounded surprised to be getting my call and directed me to an Edgar Aguilar (800 481 4999) a supervisor at Cust Svc.  Told them to take me off their list and change policy so they follow the law.
