Almost impossible to get through. Even calling when they open at 8.00am involves more than a 30 minute wait. The call back option can take more that 2 hours despite the estimate stated of 30 to 55 minutes. Then the call back involves waiting a further 20 minutes. Very frustrating because of the amount of times I have had to call due to errors Scottish Power have made on my account which are numerous. Conflicting advice given. It took me over a year to sort a problem when Scottish Power mixed up meter information and closed down my account instead of a neighbours. There are currently problems over smart meter installation. I've had enough and am about to change to Bulb.
