Unprofesional customer service to blacks

It shows this two cooperatives don't want to help me with my request, all CSC knows is to phone me and promise heaven and earth after the reviews but they don't deliver on their promises, they are quick to blame Nedbank as their client. I was phoned by Elroy from CSC we didn't see eye to eye because his concern is that I should apologize for saying that they give bad service because I am a black person and they are ******, so he referred the black manager to speak to me whom I forgot his name and he promised me to sort everything immediately, even today nothing has materialized.l think my skin colour it's a problem hear as my case is not prioritised may be if I was WHITE everything should have been sorted first time, maybe it's time to go on different media platforms to expose this CSC and Nedbank about their bad customer service towards black customers.
