Green Star Energy

I left this company eight months ago as I could no longer cope with thier shambolic administration. They told me not to stop my payments till I received a final bill and kept taking my money for the next six months. At the start of June I started trying to get my money bac, I was told that it should take up to 4 weeks. 10 weeks later I haven't had my money. or a final bill and they can't even tell me when I am likely to receive it. Yet I have had countless lies and broken promises from thier staff as I have repeatedly called them.
