City of Cape Town Allan De Jager useless

The City of Cape Town have forced me to replace my credit meter with a prepaid meter by threatening me. If I opted not to take the prepaid meter then I would have to pay for a prepaid meter to be installed when my credit meter becomes faulty. So I had not option. They put the meter in but on the wrong, more expensive tariff. So when I bought my first 600 units I didn't get 600 I got less. So I complained. So instead of them giving me the outstanding units they waited until I bought units the next month and then added the units to my token. But I also bought only 600 units in this next month and because the outstanding units were added the system registered that I had bought more than 600 units and therefore charged me the higher rate for some of the units above 600. Which is wrong. Allan De Jager from the municipality doesn't even understand how their own tariffs work.
