Extremely poor customer services, I m surprised they are allow to do business in the U.K. They never follow through what they agree to do. I had numerous issues with meter reading when I moved to my currently address, they were constantly overcharging and ignoring the reading.It took 3 months and I m still not sure if it accurate. Then I called to say that my old flat will be empty and I wanted to reduced to direct debt, yes they said - new agreement was sent etc, they still continue to take the same direct debt, even though I have a smart meter in that flat they keep telling me asking me to send a meter reading. I asked them to change my email account so I could set up online account, - yes we can do that for you Mr. …. Guess what? Still not done.
