Changes to my Electricity account

Hi<br> <br> On 30 October I sent email to query changes made to my electricity account without any notification to me. To date I still have not received a response and this issue has not been resolved either. <br> <br> My account number and account name was changed without notifying me. I never received account at the end of September, so I made and estimated payment. In October I received my bill, with a new account number, change in name and an overdue amount?? I then sent mail attaching proof of payment and querying the changes.<br> <br> Why have an email address for queries if no one responds to these mails?? Why have an auto rely stating I will receive a reply within 14 days, when 2 month later i am still waiting??<br> <br>
