Terrible service delivery

I have a damaged municipal sewage pipe which runs through my property of which is also blocked about 200m away from my property. I called in on 9th Sept 2021( Thursday) to lay a complaint where I was told that someone will come out to assess within 24/48 hours and also given a reference number. On the 13th of Sept 2021(Monday) some municipal workers did come out to assess and informed me that the main sewage line was blocked and needed to be jetted with a high pressure machine. One week later my wife makes another call to enquire about the situation of which she was told that the existing ticket was closed and she got a new ticket and was told that the matter would be escalated. Two and a half weeks later still no arrival of any municipal workers to attend to the matter and unblock the sewage line. The blockage is causing sewage to leak onto my property of which is highly unhygienic not to mention the stench. I have kids and old parents who are subjected to this terrible conditions we are now facing. We cannot even open our house windows or doors due to this. Are we supposed to live like this whereas we pay our rates on time with no defaults and this is the terrible service that we are handed. Totally unacceptable!!!!
