Incorrect Water Meter Reading AGAIN

What is wrong with the Accounts Department at the Buffalo City Municipality? They do not answer their phones and it is useless going into their branch in Gonubie as they cannot help you. Last month, they finally sorted out my Water account only to find that this month's account is once again INCORRECT. I take a weekly reading of my water meter and this is handed into the Gonubie Municipality on time once a month. They have now done my reading dates from June. Come on, surely somebody must take responsibility. Buffalo City is meant to be a Metro!!
