Incorrect billing

Hi, please help. I have tried for months to get a proper rates and water bill from Ekurhuleni.<br> <br> There are no readings on the account I get from Siyakhokha system, and there is no evaluation for the property. <br> <br> I call your call centre, it takes 20 minutes to answer a call. They say they have fixed it but another month passes and nothing is done - no water meter readings, no valuation amount reflected. Please, what can I do to get this sorted? I want to pay my bills. I don't know what to do any more. Thank you
