Wrong information, lack of accountability

Someone came to disconnect the electricity at my home despite full payment made based on my query of amount owed and information given by the municipality 3 weeks ago. At the time of the query I was told a low amount. I said that can't be right because we have an arrangement with the municipality to pay rates owed. Then I was referred to another department who gave me a higher amount but lower than usual. This made sense because we pay more than required each month. I paid this when due. <br> <br> After the threat of disconnection, the man in charge of accounts said there was still a high amount owing. I went to the municipality to pay it, with their error of the disconnection fee charged to my account. This also costs in working hours and petrol. After the maze of trying to park, there is an overwhelming stench of feces and ******* everywhere. When querying my account with this man in charge, he said he isn't responsible for wrong information given, for the disconnection fee, and he can't do anything about an ongoing complaint that they send the account to the wrong person - referred by to another. The staff were courteous but unhelpful. Who is ultimately responsible at the Municipality?
