I was told last year in August that I owe them £4600, after they took out over £400 as a monthly payment, after I contacted them they refunded my money back and still demanded the balance, I then contacted the energy ombudsman, who investigated and found that they claimed that I used more gas than electric in the summer, but I used less in the winter(the electric was just over £400), I queried the amount but they insisted I was wrong and they were right, this month they were told to recalculate and my bill is now £423 for last year, the ombudsman said the meter, which was new was not working correctly, but they will not admit this, they were meant to send me a personal cheque as compensation, I am still waiting for it to arrive as they told me it was sent out on the 7th of this month, I think it was sent on a camel via Timbuktu?
