Hello, we moved into our new build flat 2 years ago and set up straight away with Npower. for the first year we were paying just £20 a month for electricity only, then suddenly after a year we got a letter saying we owe £300 and our bills have gone up to £120 a month. after looking into it it turns out the MPAN number on our bills is our neighbours meter. We have now been waiting 4month for NPower to send someone out to clarify that our Mpan number is not the correct one and every time i ring up they just tell me they are waiting for someone to get round to it and all i can do is wait! im worried the longer it takes the more we are going to owe them as our neighbours flat was empty the first 6months so weve definately used more elctricity then him. is there anything i can do to speed them up so i can get it sorted and change to a better supplier?? thanks in advance for any help
