Terrible customer service on the phone. Initially the man at Scottish Power who answered my call started out friendly but he was reeling off numbers and figures to me so quickly that I didn't have a chance to actually ask questions and take it all in. So when I did ask him to explain things to me I got a very huffy response as if it was too much of a trouble for him to actually do his job and explain how their service works and at what costs. When I asked about prices his answers were very quick and he bypassed information that I actually needed to understand. After another impatient response from him where he actually said, "Ugh, I've told you all this before! Now we are going to have to go all the way back to the beginning if you actually want to do that." (It was in a way that sounded like a teenage tantrum) I decided I didn't want to sign up with an energy company who had staff like this. I went to an alternative company who had much better customer service and explained everything thoroughly. They also informed me that some of what Scottish Power had told me was actually a lie! Would not recommend them at all.
