Pathetic Service

I have had the most pathetic service at the Shoprite in Newtown Junction, as per the catalogue "Buy any 4 Cadbury chocolate for R29" however when I got to the till it did not subtract. I advised the teller that the items did not subtract on the slip, she then called another idiot who doesn't know a thing, this other stupid lady comes to show me the pamphlet and says "you took the wrong flavours it has to be the same as per the picture" then she decides to fetch the flavours and starts subtracting mine. They also had the audacity to say we are keeping up the line just for chocolates. It was a nauseating experience......
