Economy Energy /Grant Thornton Issues

billeted

I received an e-mail from Grant Thornton/Economy Energy 5 weeks ago with the outstanding balance of 1100 pounds supposedly owing to Economy Energy. I was in dispute with Economy Energy over incorrect meter readings and of course as soon as EE went bust OFGEN wash their hands of it. Today I have received an e mail saying I havent got in touch and it will be in the hands of Debt Collectors if I they dont hear from me in seven days, I immediately sent a reply to them which BOUNCED, Rang the number to confirm e-mail. Re sent it and it bounced again.Rang them again asked for a correspondence address and was REFUSED. Won`t go into full details but the condescending snotty woman said to me "well you have to pay your debts! At that point I insisted on her name her supervisor and she refused, Needless to say call was ended. How do I stand legally? The amount of energy consumed according to their readings are well disproportionate to my usual consumption and my current consumption with anohter (decent) supplier. There is an obviuos error in the meter readings. Becaiseuzse OFGEN have no input now am I !!!!!!ed? PS dont dispute gas owed justbthe electricity
