Problem with the Municipality Storm Water and Building Inspectors

I am trying to resolve the storm water issue with the storm water and the building inspectors since March 2019. I am In the Silverglen Drive area. My 3 neighbours at the back does not contain their storm water as a result I am bearing the brunt of higher insurance premiums and all the inconvenience caused. No body is taking ownership of their roles and responsibilities which they are getting paid for. Its passing the buck from one department to the other. (from Storm water to building inspectors). Since 2019 my house was flooded 3 times, my boundary wall collapsed 2 times and to date the issue is not resolved. Since 2019 I engaged with the building inspectors (Molfphe Lakeu, Mike Radebe, Daniel Pantesaib). In the storm water department I engaged with Gregory Williams, Karen Ronne, Sifiso Shabane, Mbalenhle Dlamini, Sandile Mdadane. All these municipal workers are a waste of space and oxygen. No one replies to your calls or emails. The worse guy to deal with is Sifiso Shabane. He is sitting in the position but does not know whether he is coming or going. Annoying to speak to him because he has no solutions, only excuses. Please if anyone reading this, please can you advise another route to get through to the municipality.
