Why do you have to award a star when no star is warranted. Npower must be the worst energy company that's ever existed. Their customer service dept is as much good as a chocolate fire guard. I've complained about the same issue for very nearly 2 years and nothing as changed. This is definitely the worst company I've ever had to deal with. It's never their fault but they're always sorry, easily said but in my opinion not meant.
As I said ...... 1☆ is far above what they're entitled to, which I could award NO STAR.
