Carelessness led to damage and poor workmanship

Hi I contracted Lomuna Group to do some renovations at my house. These were a gas installation (which was subcontracted), a new fireplace installation (connected to the gas with removal of the old fireplace), the removal of the old fireplace's diesel tank, and the installation of a rain cowl over the chimney. After lengthy discussions I ended up ordering the fireplace online, which Lomuna charged a call-out fee to come measure and plan the installation.

The gas installation went well enough and is working correctly (with a COC). However, the installer broke a shelf in the cupboard the gas line is running through, which was badly replaced (it doesn't match at all and is loose). The piping also leads a bit to be desired, and is quite untidy in places.

The biggest issue is the fireplace. They damaged the parquet flooring around the fireplace with the rubble from removal of the old one. They needed to use my tarps (which they damaged), and still didn't take the proper care despite my repeated warnings. A floor company quoted around R5k to fix this. The new fireplace is slightly narrower than the old one, so they needed to do some plaster work to fill in the gaps. This was done very poorly and left scratches and plaster splatter all over the fireplace. While we were able to clean the metal of the fireplace, the biggest issue is the plaster on the surrounding brickwork. Despite my several cleans with acid cement cleaner, this residue remains. The acid has also surely damaged the brick sealer, so I'll need to redo that also. It's left an unsightly stain on the brickwork which may need a (different) professional to clean. The rain cowl was installed (by the same gas subcontractor) but the surrounding plasterwork was shocking. Thankfully, Lomuna did fix this though. The removal of the old diesel tank was the only bit of work they did well, but it was surely also the easiest. Sadly, I cannot recommend Lloyd and Lomuna group.
