Absolute POS company. Took 10,000 watt hours off my opening reading, refused to correct their own error, and upped my payments to over £800 a month from £150. After SIX MONTHS of complaining to the Energy Ombudsman and being billed £4800 in that time, they've finally conceded that I only use £120 worth of gas a month yet I'm only in credit by £2800. Oh, and my payments are staying the same. I don't think so. Bunch of thieves.
