Since I'm on the home services and utilities kick, it's only fair to review Duke Energy!
My comments are pretty straightforward, similar to the Duke bill I receive every month. I've only had to call customer service on one occasion and they were pretty quick to remedy my issue and address any other questions I had. They also send out a box of free CFL lightbulbs to ensure your home is more energy efficient. NICE!
I also appreciate their social media involvement - they keep those Twitter feeds full of pertinent utility related information when a dangerous weather is a-brewing!
