Post net Forest Hill,Cennturion - Consumer Complaint for PostNet SA

I went to Forest hill postnet as I have been going over a period of 3 years since staying around.To my surprise this time i was told that there's a charge for certifying documents.This has never happened to me before.The delivery as well took me back,because the Zulu lady(she had no name tag she has been for a coupleof years)pointed out that it is by law and that in some white areas you can get away with it because some white people refuse,but this is a black area.She mentioned that they don't even certify copies you bring with you,meaning i had to make new copies.May I have clarity on this because I am taking this further.She was in the company of her a young lady with cornrows and a young who seemed to be highly entertained by what she was saying.
