Nose guard for Mazda CX3

I purchased a Mazda CX3 from BB Mazda in Polokwane in August 2019. They charged me for a nose guard which I never received from them. Every time I contact them, they have some story why they cannot deliver my nose guard. I spoke to the salesman and the manager and they promises to sort it out and phone me back to keep me updated. They never phone. I must always phone them. I did not request the nose guard, they told me that they added it into the total and that they do not have stock at the moment but will receive it within the next week. 6 Months down the line and they still did not deliver my nose guard. According to my contract, they added R1000.00 for the guard. This is unacceptable. Please refund my money to deliver the guard.
