First the smart gas meter went faulty. After a long wait they replaced the meter with an ordinary second hand one. It would appear that something went wrong with the notification of the old and new readings and I started to get phone calls saying I was £1000 in arrears. I demanded this in writing and an explanation showing the breakdown of how they arrived at this figure but didn't get one. I was asked if I would like to have smart meters fitted so I agreed even though one meter was already sa smart meter. I don't think the new electric meter has worked since installed. I've complained many times over the past 4 or 5 months but even though a work docket is supposed to have been raised nothing has happened. I get requests for readings but cannot give them as I cannot give the electric ones because of the faulty meter. In thd meanwhile they started to take an extra £100 from my account each month. I contacted the energy ombudsman and got a ruling in my favour and Greenstar agreed to put £670 into my account with them to reduce what I allegedly owe them, plus a good will payment of £50. I've just had £252 (the inflated figure) taken from my account so phoned them to complain, demanding to speak to a manager, but got nowhere. Over the past 6 months or so I must have emailed them at least 20 times but got nowhere and am still waiting for the meter change and so thing showing how they calculated my bill but have got no response I have informed them that their customer relations is appalling and they are a waste of space, and this afternoon I informed them that I was giving up and have started the procedure to get a new supplier. Avoid this company at all costs and if you are already with them, find someone else. The umbrella company where the payments go is Hudson Energy so avoid them as well. Viv
