Absolutely shambolic and dishonest company. First the customer service is the worst (and that is some statement) I have had the misfortune to experience, from advisors lying to being rude then hanging up it's incredibly bad. They lie and lie, yet send letters contradicting whatever has been agreed it's immoral. Worst of all the stealth charges they try to make you pay, people often talk about the third world is riddled with corruption, however it's this idealogy which allows scam artists like NPower to get away with it. Do yourself a favour, leave NPOWER immediately (just don't tell them otherwise they'll bring more hidden charges your way). If you not with NPower, they are the worst rated energy company for a reason.
