Is there a stapler that cost R168?

I was at van schaik yesterday BRAAMFONTEIN I’m so angry and mad right now and I need help about these cashiers that rob me off R100.I bought a stapler,ps chocholate and a pen.The price of a stapler is R68.00 the chocholate R13.95 and the pen R8.95,which they said I should spend R100 for activating my Intellimali card.The total ended on R191 something.But that cashier charged me R168 for the stapler.

I want my money back and I want all students activating their cards their to be aware because I could tell from her eyes that she did it on purpose..I Need my R100 back please.
