Refusing to pay balance and threatening us

DRC took my equipment to sell it at an auction, <br> They are now refusing to pay the balance of R50,000 and are instead threatening to tell my boss that I do business on the side of my normal employment .<br> <br> They are giving bad attitude and are saying they bought the equipment for less money regardless of them agreeing to R150,000.<br> They paid R100,000 and said they would pay the R50,000 when I give them NATIS documents and now they do not want to take the NATIS documents and are saying they have sold machine to another person without documents.<br> <br> I fear for that person because he/she has been robbed as well just like me.<br> I want DRC to pay my money that's all<br> <br> <br> <br>
