My smart meter was faulty and giving readings varying by 1000kwh on a daily basis. After a number of phone calls, email and complains they have agreed to replace it but I kept getting incorrect bills. Also they replaced for old type meter. 5 months later the issue was still ongoing, so I made a complaint to CEO which was passed on to Directors Complaints department. I subsequently got contacted by one of them who was more incompetent than normal customer services. He was supposed to look into this and come back to. 8 weeks later no response to emails, etc. I will be moving to another supplier, as don't have any more time to waste.
