Unfair treatment don’t know if it’s because am black or am a women

Someone drove onto me to on the passenger side.I took it in at pronto to get repaired well the door is properly fixed the car had a rough texture on it.Cause I don’t know anything about cars and am the one that collected the vehicle when I got home my partner assessed the vehicle only to find that they didn’t polish it.He insisted that I take the vehicle back to me.Since I work far I called them and I asked if I could bring in the car when I come to rustenburg they agreed.Well I took it in left the car and told me to come back after few hours when I get back the texture of the vehicle is still rough I asked them again than I saw one guy getting ****ed the other said Ohk we will fix it.Only to find that they only wash the vehicle and didn’t polish it.One of the employees there approached me and told me they removing your car again and they didn’t even polish it.I got ****ed than I left I know it’s because am a women or am black but they take advantage.
