Knifing company towards agents working for them

This concerns a new development in Centurion, called Thatchfield Ridge. I was given a mandate to sell new houses from plan. I have sold 6 units of between R1 890 000 and R2 100 000 successfully (all got bonds) in two months (Nov, Dec 2018), I am still waiting for my commission to be paid by this company. Be careful doing any business with them.
