My caller ID comes up as Superior Energy but when i tried to call them i get nothing but music playing.

I think they recently got permission to provide electricity in the Eastern PA area.  I have had phonecalls from them as well and generally ignore them.  I believe they also purchased some retail gas (propane, etc.) distributions from Sunoco so if you had a contract with them as a supplier in more rural areas they might be calling to ask if you need your tanks refilled or if you want to sign up with them for electricity.

Just moved to PA from CT. Receive these phone calls regularly. Never anyone on the line when I pick up. Very annoying, especially now as there is a recovering heart surgery patient in my home. The call today interrupted the first decent sleep she'd had in almost two weeks.

What do I need to do to protest these annoying calls in the strongest manner possible? There is never anyone on the other end of the call when I pick up. What's the purpose? When I call back, there is one ring and then recorded music.

glad to hear that I was not the only one.
