Green Star Energy Hell. Do not deserve 1 star. Avoid or switch before this happens to you. I have had an ongoing issue since my new gas meter was fitted in April 2018 and it still hasn’t been registered with the National Grid! My gas bill has escalated out of control £1200.00 DR over a 6 month period (for a single person in a 1 bed flat). What are they doing about it? Absolutely nothing! Complaint after complaint and failed promise after failed promise since December 18. THey even ignored the Ombudsman so I am having to make a further case against them. I am being held at ransom by this company through no fault of my own and unable to change supplier until my meter is registered and this is resolved. I have contacted my local MP, Which, Watchdog and Guardian Consumer support because this company are so corrupt in their dealings with their customers and all of the poor reviews really concerns me.
