These people stole my R30 000 Samsung Front loader 18kg washing machine and 9kg tumble dryer combo

These people stole my R30 000 Samsung Front loader 18kg washing machine and 9kg tumble dryer combo. We called repeatedly and they insisted they don't know where the machine is, even though I have the receipt showing they took possession of it (the 1 they say you have to present to collect the machine) and even claimed anyone could have collected it. They eventually agreed to give me another machine in its place and gave me a pathetic (old, damaged and ugly) 7kg Toploader that wasn't even worth R2000 to replace my machine (I wonder from where?). When I started talking about a lawsuit they told me that the owner had died and that there were many similar stories so they wished me luck in getting anywhere with it... How much money have they made *********** people's appliances???
