Took 20 months of constant requests to get a bill and then it was clearly wrong. Gave us 3 different account numbers during this process and a starting balance of -£800 that never existed - we were new customers with a £0 balance ? Regular 30-40 mins plus on hold while trying to get through and talk to someone, countless promises made to resolve our complaints then open complaints closed down with no warning. They lost our meter readings and couldn't even tell us which tariff we were on ! After 26 months we have still got nowhere, our case now referred to the ombudsman. HOW IS NPOWER STILL ALLOWED TO TRADE ? THIS COMPANY IS AN ABSOLUTE DISGRACE !!
