We moved house back in October and signed up to Npower in November. When we signed up the cost seemed a little low but hey who was to argue. How ever they had hooked me in. The next quarter the bill came in and bang a huge debit in the account and so the DD was increased from £40 to £98. Ok I could see that that original one was way off. Then we move on a few months to June. I get a call from some one at Npower dear Mr X we have a problem when you set up the account the DD for the gas was never set up! I was totalled unhappy. However before hey could look into it they wanted my current readings but I was at work so they said they would ring back later that night. He also offered to look at the tariff to see if they put me on the lowest one. No call ever came in. A week later I get a call from someone who goes through the situation and says well you now need to pay £178 per month plus extra to cover the deficit left so it is now £230 per month so from £40 to £98 to £230! Aft the end he said is there anything that he could I said well two things an apology would be nice, the reply was its no body's fault sir, and then I explained that the first person who rang offered to look at the tariff and after some arguing he looked and said oh you are on the lowest one good bye. When I get home I get an alert from equifax Dr Mr X your credit rating has dropped from excellent to poor as Npower have black marked you as none payment for 6 months. So obviously the person at Npower has taken upon himself to report me to Equifax when until a week earlier I had no idea and they had not said anything. So I complained to Npower and a week later they rang and corrected the Equifax scoring but only for three months so my score only rose to good. They only offered £50 as compensation. This week my wife and I went for joint account guess what refused and what is worse they cancelled my contactless card and gave me a basic one due to the scoring. Finally after all this I went online to make sure the DD was set up and guess what there was a section saying our lowest tarriff could save you £232 per year switch here. So there was a lower tariff after all! So all in all a terrible experience after I had done nothing wrong. The person I spoke to had obviously taken upon himself to report me to equifax when I had technically not missed one payment. Never use Npower reel you in and then take you for a ride it will take months maybe years to get my credit rating back to where it was and I still owe them £500 so are stuck with them until I can pay it off
