Hugely overcharged by Ecotricity, I am a person living alone and they were taking £171 per month - supposedly because I was in arrears although they couldn't explain why I was being charged so much. Couldn't access my bills online because of a technical glitch at their end and when I phoned them, I spent ages on the phone with a stroppy- teenage-sounding girl who was unbelievably rude and unhelpful and left me hanging on for ages before finally cutting me off. I switched energy suppliers that very same day. I only wish I had switched earlier, it would have saved me a whole load of money.
