Bad service from a racist service manager

Our vehicle was serviced at McCarthy two weeks later the vehicle was towed back to the dealer for a radiator leak the service agent told me vw will pay for the damage because the vehicle is still under warranty he did not even phone me he just send me WhatsApp pictures and tell me vw is not going to pay i must pay R11 000 to replace the radiator because the vehicle was in an accident i told him the vehicle was never in a accident when i got at the dealer and start asking questions about the damage he called the service manager who didn’t like my questions a real racist white man who thinks nothing of none whites he told the service agent take the car off and put it outside if I don’t want to pay but he did not even put a claim in at vw sa the way i was treated at this place by these people on top of it when i contacted vw customer service they just listen to his story three different stories as to what happened to the radiator this service manager thinks absolutely nothing of none whites because if i was white he would never treated me like this they just put my vehicle outside and i had to make plan to get the vehicle home and fixed they does not even deserve a one star
