Racist terrible car servicing experience

This service area is the pits, racism still thrives in here. My car was fifth in line to get serviced before opening time at 7am but I had to wait the whole day for it. Inside the workshop, there are two queuing lines, one for whites and another for blacks. The white people whom brought their cars after ours the "Black" people were serviced before ours. How does BB allow such a thing? I think it would be better to reserve this branch for whites only and not include us, because years into democracy racism thrive in places like this. And when you raise such concerns with the consultants, they play it down with those smiles. I regret coming to this branch, I have been to different service areas in Cape town, joburg, Durban, polokwane and all but I have never seen such treatment. I suppose I have to suck it up, it's owned them and we are supposedly trespassing.
