I phoned this company for information and wanted hard copy by post of what they were offering, for comparison with rivals. They asked for my bank details, apparently for some kind of confirmation of my identity or status, which worried me, but I gave my credit card details as possibly safer. What they didn’t tell me is that I was thus automatically signed up with their firm, and they at once took over my fuel supply. Citizens Advice Bureau assures me that this is a case of “erroneous transfer”, with no liability on my part. I have had phone calls almost every day, sometimes twice in a day, wanting me to withdraw my earlier review of their service. Fortunately, on advice from my bank, my credit card was cancelled. Be careful !
