missditz: I have spoken to N-power and they are telling me that the 1980 limitations act over-rides the billing code and that they can chase payment up to 6 years back.
So, am i best to write everything down and send the letter of complaint by post?
On the first point perhaps there are some legal eagles lurking who will answer the narrow point.
On the second point the answer is yes. The first assertion should have no bearing until the Energy Ombudsman has made a decison, so get that letter out strictly in accordance the NPower complaints procedure.
While or before you do that, contact NPower by phone and inform them that you dispute the account, are in the process of submitting a formal complaint in writing and expect any enforcement action to be stayed until there is an Energy Ombudsman decision. Make sure you note very carefully the time and date of the call and the adviser's name. Quiz the adviser about whether the call is being recorded, what is the process to obtain a copy of the call, what is the data retention period for the recording and make sure you get the adviser to check back what you say so that you are happy the adviser understands (for the tape) your proposed actions. Unless the call is an expensive number stay on the line until the adviser has answered the call recording questions and if the questions are not answered submit a seperate written complaint on that competency issue. Turn your nightmare into NPower's nightmare.
I strongly recommend you do not get sidetracked into making the complaint by phone, but that is your call.
I also suggest that you make some prudent financial provision for whatever is the eventual outcome.
