I have never had a problem with Npower n relation to their delivery of fuel or with meters or meter readings. However, I have recently had two issues with them which I've complained about and have to say I find their customer service and the way they deal with complaints is very poor. The first complaint was about an agreement they made about the issuing of bills to my wife who has authority to manage my account. As regards this, several shortfalls in customer service occurred - 1 In error they stopped issuing bills to my wife 2 After correcting the error, they again stopped issuing bills to my wife without my consent. 3 After receiving an acknowledgment of my complaint sayig they would respond within 7 days, they did not respond. I only received a response 7 days after submitting a further 2 complaints. 4 The responding complaints handler claimed no bills had ever been issued to my wife and closed the complaint without my agreement. 5 After complaining yet again Npower stated they HAD restored their agreement about the issuing of bills, but they hadn't. These shortfalls were actually identified by the energy ombudsman after I referred the issue to them. The second complaint was in relation to direct debit payments. when renewing my tariff with them. The following shirtfalls I belive happened are - 1 Based on meter readings, they quoted me a monthly payment £1 less than I had been paying which persuaded me to sdtay woth them. 2 Two months later they invreased my payments by 30% saying that my current level of payment would not cover increased usage during the winter months. 3 Three months later, without my consent they gave me a refund as I was in credit, presumably therefore, paying too much. They did not reduce the payments. 4 I response to my complaint about this they stated thst the monthly payments WOULD remain as they were otherwise I would fall into "debt" over the winter months. Ths complaint was again closed without my consent. 5 Some time later I complained again about this and have never received a response to this complaint. 6 When asking if I could pay by standing order rather than direct debit so that I could have some control over my payments I was told that I could do so if I wished. However, a £90 per year discount is given for paying by direct debit, but not for standing order. Overall Npower conducts some aspects of its business according to its own rules. They refuse to change these as per customer;s preferences, stating that they are a matter of policy or "business decisions". They refuse to give access to these and they are not stated in their terms or conditions. They offer no explanation of the errors they make and offer no assurances about the likelihood of errors recurring. The energy ombudsman service, Ofgem actually supports them in this.
