I only wish I had read these reviews before changing to this awful company. Started off on a direct debit plan of £129 all of a sudden this was increased to over £200 with no notice! I have called every month to be assured that they have amended the amount back then the next month we are back to square one. My smart meter states we use between £80 to £100 a month but they still want to charge me over £200 a month to build up the credit at my expense and into their pocket. Happy to pay what we owe and when I suggested that I pay monthly I as told my terms would change and I would have to pay more! The customer service is appalling not helpful and feel they read for a script don't come up with a resolution this is when you get through of course. Been on hold for over 30 minutes and requested call backs that never happen. Can't wait to end my contract. Don't switch to this company!
