Absolutely horrible

I have signed a contract with these people to do built in kitchen cupboards at my moms house,we spent over R35000 after we asked them to also break out a wall dividing the kitchen from the lounge to make it an open plan.They took so long to deliver,eventually when they were doing the final touch ups,5 days after installing all cupboards it all collapsed from the walls and they refused to come fix the damages and only want to compensate us with R10 000 starting from 2021. They have fled with all our money without completing the job.
