Poor customer care service, Mazda south Africa

I have recently launched a complain to Mazda south Africa customer service, regarding not getting spare parts which were ordered by Technostar on 25/10/2018 up to date they haven't received parts. On 14/01/2018 i draft and sent an e-mail to Mazda customer care specifying my grievances and they haven't reply and letting me know what is the delay for not delivering parts in time. It been 3months my car is with panel beaters because Mazda south Africa have no sense of emergency when it comes to their customers. They just ignored me without giving an explanation. This company is very arrogant and disrespectful, they do this because of my Race(African). They treat me like i didn't buy this car. I never see myself buying a Mazda car again. This is not the first time i had issue similar to this one in 2015. Mazda south Africa have a poor customer service. They don't solve any issues, they are *********** customers.
