moved into a new house in June 2014, up until today I still haven't received a bill. it has been problem after problem, firstly the opening reads given to them by British Gas, they couldnt get right and apply to the account correctly, took them 6 months to get the account correct and the serial numbers for the meters confirmed with thier "bak office team"!! I was expecting a bill in december in line with their direct debit 6 month billing cycle, but could see online, bill wasn't going to be generated until April 7th 2015, rang to be told that there was a problem with the account and there was nothing they could do!? Bearing in mind, this account was a brand new account, with a new house, with opening reads given to them, bi-weekly meter readings sent to them by myself, and yet they still couldnt generate a bill. 7th April came, SMS received to say there was a problem with the account (surprise surprise) and they would fix asap. log in to online account to see next bill is due 1st July!?!?!?!?! Rang to find out why this was, billing department rang their complaints department who fixed something on the account which was apparently minor. Cue the complaints department swapping the elec and gas readings round, screwing my bill and the past 10/11 months of meter reads gone! Only found they had made the mistake of swapping the reads round when I asked why I owed them £225, after working out I owed approx £600, account in credit by £850!! Rang back after getting cut off, to be told by billing that it would be 10 days to investigate (their) mistake on the account, after speaking to the web team and speaking to a very helpful Simone, readings have been rectified today and bill should be generated 3-5 days. After all this, this is no way to, A) run a business and more importantly, B) treat your customers. There's no excuse for the ineptness on N-Power's behalf and all the apologies in the world cannot make up for being left in the dark, not knowing whether you've over/underpaid your bill. bearing in mind these show up on your credit scoring, its extremely important they don't mess anything up. The £50 exit fee per fuel is looking extremely attractive as I'm not sure I can hack another 2 years with N-Power. Avoid like the plague!!!
