Hi,
Eventually got a dedicated worker and nos from Scottish Power and the same from the energy people. It transpires that I was still on the records as being in dispute and therefore they hadn't been taking any money (I have to take some responsibility for that although thought my husband had paid the bills) and they don't have to send reminders!! Even though I have been callling all during the year, had meters changed etc I had no idea.
It has been worked out that actually I am using roughly the same amount of units as the average house, for gas and elec, but because I hadn't paid anything thats why I got an enourmous bill again!
Apparantly because I agree that the units average out over the year I now have to go to the Ombudsman regarding customer service. My complaint is that at no time have SP contacted me and at no time when I have contacted them did anyone discuss my account with me and explain why the units were so erratic. In addition to this they have now told me I am not on a cheap tarrif and that I can get it even cheaper if I register on line.
I am just about to put pen to paper with my official complaint. Will let you know how I get on.
