1 star is far too much for this company, I was moved to them because of my supplier went bust in October and as my supplier had already increased my monthly charge from £66 to £99 for the winter months and I was in credit of £242 before they went bust I didn’t expect a problem, as we were suppose to be protected by Ofgem!. I never received a bill from shell energy but I supplied meter readings every time I was asked and continued to pay my direct debit like I was asked to the higher amount for the winter months! 5 months later shell send me a bill that says I am being charged £847!!! For the months they have taken over to now! Not taking into account the money I have been paying as asked £99 a month they have charged me £847 on top! I straight away emailed to asked what is going on and shells response is they charge more than my previous supplier and nothing I can do! At no point was I ever told shell were going to charge more than twice what my supplier who went bust was charging me! I do not use any more energy than previous years. So now she’ll want £380! A month! To cover the cost of what they want to charge and the amount they have now put me into debt! I have complained and they have tried to say it is my previous supplier problem they should have told me to put my payments up! How would they have known what shell were going to charge?? So I have complained and complained and got no where only other than they have offered me £50 good will for a short fall in their service!! I have refused this and asked for a deadlock letter so I can at least get some help from the ombudsman because I cannot take the stress anymore and they are just plain rude and not helpful, I feel I have been taken advantage off by being put with them and I cannot leave and now I am in debt to them. I have today raised the complaint to the ombudsman and gave them all the evidence and what a surprise I have had an email to say shell have been in contact with them! Within hours “to query the acceptance of your complaint”
