Wrong pricing on a barcode

I think it should be last time I buy something from someone who doesn't have decency of apologising for the inconvenience, ok not to speak about the consumer rights as Mr Price in Rosebank failed to comply with the Consumer protection Act 68 of 2008. I just bought a product with R10 extra and when I call to find out why am I daily ******? I saw my receipt at home, I called to enquire and manager named Shaun said ok come over we fix it, I get there they say \give him R10\" no apology for robbing me? Question if how goes Mr price fail to apologise to me, coz I am young, male or Black? I want Shaun to act accordingly on this case ASAP, I will escalate this matter if I am not happy for my money. <br> "
