I decided to contact the Citizens Advice Bureau today, as I am running out of ideas on how to deal with this situation. The woman I spoke to was astounded at the amount of money paid by me to Scottish Power over the period of my complaint. She asked Isn't that a bit excessive? She attempted to call them and was of course given the runaround. Eventually she was put through to someone who told her that we were considered bad payers. They had obviously either not been aware of the state of my account, or didn't know that we had previously been given a complete breakdown of our account from August 2000 to November 2006 by Rae Brown. This clearly shows all monies paid by me to Scottish Power. I say clearly, however it actually shows stupid entries such as - 11 months of direct debit payments as a single payment of £2200.
She asked this moron how he would explain the drop in our usage when our neighbours moved out. He apparently replied that it simply meant that we were using less electricity, ie. suddenly we stopped using 1/2 the appliances in our house. So in essence Scottish Power can simply say to anyone "you are using less appliances in your house and that is why your usage is down 50-66% on previous years" "It has nothing to do with your neighbours moving out."
She was then passed onto an Adrian Edwards who is seemingly a senior complaints advisor. As far as he was concerned we are liable to pay any outstanding amount despite contradictatory evidence, and they need do nothing. As I see it, using Scottish Power's own logic - they will not agree to us getting a direct feed to the mains as opposed to a split feed as this will 100% back my case and they will be forced to reimburse me all the money they have overcharged me throughout these eight years.
