After over 6 calls over the last 5 weeks, I was able to get passed to a Supervisor.  I told him I am on Do Not Call list and have requested on every call to be taken off their list.  He gave me 877.681.3976 to lodge a formal complaint with the company-- (American Pro Energy).  Called the number and left message with my concerns.  I also sent an e-mail to the company via their website with my formal request so there is a paper trail if I continue to receive calls
