Very Poor Workmanship

I had some maintenance work done on my property in early December and I found the work to be of a very unprofessional and poor quality. They charged me an amount of R4200 for 6 off-cut pieces of tiling (did not even get the correct size) in my kitchen, some shabby grouting around my sink area which looks very untidy, they also charged me for 8 light bulbs of which they only replaced 4 of which are not the correct kind. R150 was charged to replace a light fitting in my bathroom which was not done. The door latch was knocked off with a hammer and not smoothed. they left the rough edging. Honestly I feel ripped off as I paid the full amount and now my place looks worse than before. This has resulted in the devaluation of my property. Very poor quality of work and Dishonesty!!!
