Unneccesary Electricity Disconnection

I pay my electricity account every month as per billing before the due date.<br> <br> On the last statement it clearly said I must pay before the 18th of June 2015 and today is only the 15th. I paid it in full today.<br> <br> Every month there are new correction billing and when I ask Tshwane like I did in the past month they cannot explain what the corrections are for.<br> <br> Today they disconnected my electricity eventhough I also paid the bill today in full again. I will dispute any reconnection fee and want my services restored..<br> <br>
