Poor workmanship by Batho Pele Construction Company which was assigned by OUTSURANCE to rebuild the driveway and the boundary wall.

Good morning I wrote my compliant about the construction company that was assigned to rebuild our driveway after it collapsed due to the 2019 April floods , the same area that collapsed did the same thing in the floods of 11 April 2022 . My issue that i was frustrated with is why the very same area which the Batho Pele Construction Company was rebuilding is the one that is not holding , why not any other part , why when the driveway collapsed we saw just mud that came underneath, something went horribly wrong with the rebuilding, i am on the same level in my street with my neighbors but i am the only one whose driveway collapsed yet i am the only who had it redone in 2019 , mine should have been the strongest because it is fairly new. I am going through a lot of heartache because my car is stuck in the garage , i am busy trying to repair , then my question is why is Batho Pele Construction having a good time not even frustrated by their poor standard of work. The smaller companies who are not assigned with the big insurance companies like OUTSURANCE they do the work and they guarantee it. The work done by Batho Pele Construction Company could not even last 5 years . I seriously need my compliant to be considered. I'm stressed and frustrated. Please help me .
