Why do I pay Cape Town Municipality for refuse removaI?

I live in Steynsrust, Somerset West, and on Tuesday 15 March my black bin was not emptied, and a set of bottles in a transparent bag next to the black bin was not removed, but dumped inside the black bin. I thought perhaps the refuse people didn’t manage to make their rounds, but on 17 March nothing had changed so I telephoned the Municipality and laid a complaint. Ref ***. This is Escom-style inefficiency which I pay about R140 for. I was told that it would take a day or two to remove the refuse. Some joke, as the refuse has been left now for an entire week.
