Owner takes money for orders and not deliver

Sometime in July 2017, I bought stone cladding material for my house and paid all the amount for quantities I required. I also paid delivery fee in full. I was promised that delivery will take place in two weeks. I waited for a month and there was no delivered. I started calling employees and they kept telling me that the Owner , certain Vincent Du Plessis is in charge of orders. I got Vincent cell numbers started calling him. The dude kept on promising to deliver but nothing happened. He kept on lying about the mines and trucks jack-knifed etc until I realized that he was not going to deliver of pay me.

I then opted for a drastic step of appointing collectors to chase him for me and I got part of my delivery only yesterday. Anyone not having resources to pursue a crook buy from reputable companies and traders
