Cantu special - 5 items for R100

I left work early today and rushed to pick n pay to purchase their Cantu special as advertised in their catalogue for 5 selected items of Cantu products @ R100, which runs up until 2 February. When I got to the till, the products totaled R500 which I queried. The cashier was unaware of anything, another customer who had come in for the same thing advised that it was a printing error. I was taken to the info desk where I was ignored as if I wasn’t standing there. I eventually Left the stuff and walked out. If you advertise it, you honour the price advertised. Extremely frustrated and disappointed!!!!
