If I could give no stars I would. Terrible customer service. Appalling behaviour from this company. Disgraceful. Short version of our experience. Approx 2.5 years ago we received a quarterly bill for thousands and I mean double figure thousands. We queried this bill and was told numerous times that it was correct. We live in a small 2 bed flat.....someone with a bit of common sense could work that out. Mainly us chasing them as we wanted to pay a correct bill. Them telling us they needed to send someone out to check out meter but couldn't due to covid. 2 years later of chasing, sending pictures of our meter readings, having to turn our electric off throughout the day to do "checks", being passed on from one complaint handler to another, causing upset and stress because as the time goes by we would still have to pay some sort of bill for of course what is due however there is a big difference of paying a quarterly bill to an outstanding bill of 2 years. We finally resolve our issue and I believe this is only because I requested for a smart meter to be installed. Been receiving bills and "normal prices" - 2 bedroom prices, not electric to run a small village! Unfortunately on my error I was late on payment for one bill and a couple of days later received a phone call to say I had to pay £10 late payment fee. After everything they put us through for 2 years with their poor customer service and not being able to resolve a simple matter they still charge a £10 late fee. Scottish Power you are a disgrace. Quick to call you up for a £10 fine but not quick enough to call back when really needed for above situation.
