Misleading ad

I saw an ad on their catalogue for a Huawei Y5 lite the price was R1399, but the person that was assisting me refused to sell.it to me at that price. I even told her that on the online catalogue it's that price too, she said it was a misprint the phone is R1599. Why advertise a price for this long and not rectify it, because that catalogue had been out since 6 May 2020
