Customer service with this company is appalling. I have attempted to contact them on several occasions, eventually managing to speak to different people. My initial enquiry was to check I was not in credit as this is not practical for me currently and I do not want my money sitting with the company - only to be told I was in significant debit of varying amounts and then with no outstanding amounts whatsoever. Calls were not returned, information provided was poor, I was told I could not speak to a manager, the call was disconnected today (I was not rude and so no reason for this, I had purely asked to speak to a manager). My direct debit is apparently going to be increased from just over £50 per month to £848! I live alone, I am usually out at work, I do not leave any heating on when I am out, it is impossible to sort this out without a formal complaint and I plan to speak to the ombudsman. I would strongly advise to avoid this company in view of my experiences.
