I regret ever buying a car at Mazda

Took my car in at Eastvaal motors secunda for some issues it had that I could not identify,basically diagnostic test, no smile nothing,they treated me like they were doing me a favour. The receptionist told me my car would probably be ready round about 14:00 that afternoon, when I got there an old rude white lady told me my car would only be done @ 16:30,mind you the car was in the workshop since 7:30 am 2014/11. Today I went there again,the receptionist was busy helping someone, I took a sit #queuing, when the lady was finished she didn't bother to help me hence I was siting facing the opposite direction.a white guy walked in,and she helped him,while I was still sitting and waiting, eventually I went to her desk while she was still busy with the other gentleman. Only thereafter she helped me. As for the rest of other staff members it's like no one really wants to help, seemingly they have issues with black customers, because when their white customers walk in,they greet them,smile, but when they assist a black customer they all sour . I feel they are a service provider that must treat all customers the same. And the other thing,no one wears a name badge, unprofessional.
