Poor customer service at CMH Mazda, Umhlanga Durban.

I bought a brand new Mazda CX5 in September 2017 at Mazda Umhlanga in Durban. I was billed for personalized number plates that I asked for. My sales man Shaldon Samuel promised that the number plates would be ready in 3 months. Months went by without hearing anything from him. I enquired number of times telephonically and he would come up with stories that he is still waiting to hear from dept of transport. He does not care about customer care or whatsoever. He does not call to update me. I ended up requesting for my money back after 2 and a half years running after him. He promised to pay back my money and he even requested the banking details but up to this day I have not received my money or any form of communication from him. I regret the day I made a deal with Mazda and that sales man who has 0 respect for customers. I want my money back with interest. I cannot be paying for something I never received.
