Last month, September, my payment didn't go through. I called them twice to see if there was a mistake or if I still owed money. I specifically asked if I needed to send another payment. They said "No, everything is ok." Then this month, they sent me a huge bill for two months that I could barely pay.
They are totally incompetent, and they pass their incompetency on to their customers to shoulder the burden. They're just arrogant because they have a monopoly.
Recommendation: You're stuck with whatever power company that gets rammed down your throat. You have no choice, so just be wary of these sneaky, little knaves
