Do not refer anyone to Audi Bruma to purchase a car, you will never receive your commission

I brought in a customer on the 27th of march who was purchasing a kia rio 1.4, the deal was approved the next day. Audi Bruma got their money and the client I gave them was happy with the car. I was suppose to receive a spotters commission/fee, till this date I haven't received anything.

Always when I call them, I get empty promises.
