Incorrect pricing

We need negative number to rate pep. Went to pep home at the grove mall! Bought x6 small glasses because there was a big red price on the shelve labelled as R14.99 on those glasses, underneath the glass it was a price of R19.00 got to the till and they said no it’s R19.00 and I asked why is there big red price on the shelve for R14.99 they mentioned it’s “from” I asked where is the “from”and they couldn’t answer even with the manager they just said “ke se pep” besides given the right or better explanation, I was caught up with attitude and rudeness both the person who worked at the till and the manager
