Sewerage overflow

For the past week I have had sewerage water overflowing from the manhole on my property. No one at the city of Cape Town seems to care. I logged a call which was closed without the issue being fixed I then logged 2 more calls. Eventually they arrived on Thursday only to tell me the problem is at the main pump somewhere. I was promised it would be fixed today but still nothing. I have sewerage water flowing out of my garage as well which is now inaccessible. This is what the city of Cape Town things of us.we are with living in sewerage water
