Golden Era Cars ******** Clients to get Deals

Good Morning I once bought a car at Golden Era Cars in Gezina through a sales person - Tshepo Lebese, the deal wit the dealership is that , if you (the buyer) recommend someone else to purchase a vehicle with the dealership, you will get R4000 compensation for the recommendation, I had then put in a good word around for the dealership trying to get people to buy from Tshepo and in return to get the compensation promised, Upon getting someone, around July Tshepo promised to give me the compensation due to me as it should be, to this day, Tshepo has not made any compensation and keeps ignoring my calls, I have called the dealership to find out about this deal and for advise on how to take the matter further. I am extremely disspointd in how the matter has been dealt with as this "deal" is a **** to get clients in.
