*** service kia fourways and kis vereeniging

I have 2 bad customer service from kia motors 1.I took my car for the first yearly service to kia vereeniging.the consultant didnt check on her system if my car was on a service plan she took my just lookinv at me that im gonna pay R9800 cash.and i told her to look on her system to see that im a paying for a service plan.then she suggested i take it where i bought it which was kia fourways and by the way i stay in the vaal.vereeniging is nearer to me.i drove to fourways On my way to fourways she called me telling me shes only checking her system now and it shows that im paying for the service plan so i must come back to them.i asked her why she didnt check in the first place when i was there.so my conclusion was that im black and her words was i didnt buy the car from kia i bought it privately.according to her a young black woman cannot afford and cannot qualify to buy a car from kia direct.my advise to every1 including blacks is that never underestimate a customer no matter their colour. 2.my 2nd bad customer service was from kia fourwyas.i took my car for the 2nd annual service got there my odometer was on 86000 was told its still early which i also umderstood.took it back at 90000 was told its still early cos the first one i took it late which was 78000 so 3000 late so i had to bring it back atleast at 93000 so yesterday 30 october 2019 took it back was told its passed the 90000 odometer i must pay for the service from mu own pocket.why do they treat customers like that why didnt they service the car when i brought at 90000 already?and the receptionsit is the very same lady who told me i must bring it at 93000 now that im back she acts as if she doent know me.
