Oh yes, another possible organisation to turn to is CONSUMER DIRECT and if they can't help you they might put you through to someone who can. Email them. They helped me to get a year's free electricity when Southern Electric cocked up my bills and FORGOT to charge me for a year when I'd even given them my DD details! I refused to pay for a year's electricity in hindsight. Got through to a senior person who just wrote it off. Brilliant!
