Kia East Rand service to Black people the worst

The dealership is as useless as they come atleast to its black customers. The only black sales person Tseko was helpful and willing to go the extra mile for us but his efforts amounted to nothing because his ***orkers were nothing but ******. We waited for 40minutes to get our car evaluated for a trade in price and when this Phillip guy finally came he was not attentive and wanted us to chase him behind to give answers. Kia must do something about this branch. Black people are being treated like trash and we buying not renting these cars. My question is that these white sales people are they doing this because they don't want to assist black clients or they are doing this to sabotage a sale for the only black sales guy there. I want KIA to call me and apologise.
