they saying calling for cap program duquense light how can they pose as the light co name !!! ask for your account number on bill etc !!!

Showed as missed call on 4th of July. I called the number,  says disconnected.

Any busy else getting these calls about their energy account with 'Duquesne'?  More importantly, anyone have any luck getting them to stop?  I have asked every time they call for them to put my number on a do not call list only to receive multiple calls in the next hour.  Can't get any of the operators to cough up a company name other than the 'Discount Center' so that I could file a complaint.

Showed up on my caller id.
