Shocking customer service, abysmal response and useless dispute resolution. Failed to update my details, even to the point they said I wasn't a customer, despite taking my money by DD. They used false meter readings to bill, blaming me for the previous supplier giving them incorrect information. They also put me on a standard tariff when I asked for a fixed tariff. Oh, and when I moved home they continued to charge me for a homecare service on the previous property, despite being informed of my new address AND they set up a new service for the guy that bought my old place, so it's not like they didn't know. Absolutely the worst energy supplier - and when you consider how bad some of the others are, this really is a dreadful indictment.
