Accounts Department are useless!

I have logged a query with City of Joburg under *** in August about incorrect readings on my bill and up till now there is no feedback on this case.

They are also taking estimate readings and I am being overcharged after the correct readings have been provided. They have now gone put in the incorrect readings again and tell me that I still owe them R937.00 after me paying them what I owe them. They are making these errors by putting in estimate readings and I have to pay them for this?! What kind of *****s do they have working in the accounts department that they cannot see that actual readings have been given but still take estimates???!!!!

They refuse to do their work properly because they work for the government and think that they can just ******* people without getting caught and when we do pick up their mistakes, nothing gets done about it. People should be fired from this damn place and get people who know what the hell they are doing. They owe me a refund but refuse to sort it out instead they tell me I owe them money.
