Bad service from nomaganjane construction, nelspruit

I had two jobs done by this company at my house in lows creek. The last job was Dec 2021. I informed the owner that the one room where the fan was installed could not even close, the brand new toilet leaked and the bathroom tiles was not according to the pattern. I send him several messages and he promised to come and fixed but it never happened. Will never use this company again. I still see the bakkie driving in Nelspruit but can not get hold of the owner.
