I was with Scottish Power for 12 years. While I was with them they gave good customer service. But try to leave them and their customer service is really appalling. I explain my difficulty in paying in full, I agreed a repayment of my final, but I was hound with messages and phone calls every day until I gave and paid the outstanding money. My daughter and I had no money for food after paying the bill. I would not recommend Scottish Power to anyone considering going with them.
