This is my first time writting a review and have to say this company is terrible. I have not been good in giving my own readings but whne my bill doubled I felt I better to reduce my payment. There is only one person living in the house and they expect £130 a month for gas and electric. They have lost the first meter reading and they are 300000 units out. So I took the trouble to get the first reading and then gave it to them and you would think with a bit of calculation everything would be sorted. No!. I am now getting emails stating I have I am due them money. So as a result I have STOPPED payments and said that as this is their mistake they wont get paid till they sort it and I am now going to change suppliers however I am going to have the hassle of explainging why I am due the previouse company money. What a nightmare as I never owe money. This company is slow inept and totally unorganized. Dose anyone have the details of the management of Greenstar energy as I am wanting to take it to the top now. I worry about vulnerable people how many people are being overcharged this way.
