I wish we had NEVER gone with npower! We have a MASSIVE DEBT now because of them. When we moved house we called npower to pay our final bill which we had been waiting for, for about 8 months because they hadnt been able to bill due to a problem with their systems. We were unable to pay and called on numerous occassions however npower could still not provide us with a bill. 2 years on and we have received many bills all of which have been different to the next which we have disputed, we have had bills for periods we were not living in the property, bills with different account numbers and the wrong address. It has been to the complaints department 3 times and all 3 times the complaint has been closed without my knowledge. So I took it to the energy ombudsman who to be honest werent really much help as we were hoping for the bill to be written off as n power have never been able to produce a correct bill in the last 2 years so we are not at all confident that the final bill they 'say' is now the correct one is right. The ombusdman suggested to npower a small amount of compensation, an extended re payment period to suit our needs (which actually isnt any different to their standard repayment period) and now we have another bill, to pay each month of £50 which we would never have had, had n power taken payment from us when we tried on the numerous occassions to pay and then they had the cheek to turn around and say "well you should have kept the money back" .... in two years alot can happen and circumstances change, we had the money then and THEY wouldnt take it, 2 years on we dont have that sort of money now and we cant afford an extra bill of £50 a month either. We are still not confident the bill is right and demanded our account to be reviewed through the back billing code of practice which n power did not seem to want to do atall and took my partner alot of arguing with them to say they would do it, this is our current situation at the moment and we hoping something comes from this otherwise I have no idea where we go with this ... I am so angry at n power that we are in the position we are in at the moment and all because of them, their fault not ours. I would NEVER use n power again and i certainly will not be recommending them to anyone in the future.
