Scottish power would not send someone to read my meter .I could not give them a reading as my meter was situated to high and had a cracked and I am disabled glass so could not read it ...after 100s of phone calls and emails to resolve this still they did not send anyone to sirt this out.so I carried on paying estimated Bill's for over 2 years ...finally they gave me a smart meter but then decided to estimate what i should have paid the previous 2 years .under the guidelines nobody should pay estimated Bill's over 12 months old .this is the worst energy company ever.no customer service at all.full of fraud .I've now left this despicable company and recommend that you avoid this company like the plague
