Bad services

Bad service after I reported my boot didn't lock and was asked to bring in the car for a technician to check and eventually found the problem and asked me if I could stay to fit the boot lock unfortunately I couldn't but they suggested I go to the nearest branch of which I communicated with Gariep Motors. We had an agreement that I will bring in the vehicle once it's time for service because driving up and down to Kimberly from Kathu is costly. All to my surprise now the car has to go for service and the warranty period is over they can't fit it i must pay for it. I'm so disappointed with their service. Bad bad bad I don't know if it's because of I'm black.
