False Adverti*****t

Yesterday Evening i went in the store to buy Huggies Dry Comfort nappies, however on the shelf the price was R159.99 and when i got to the till the price went up to R189.99, which is false adverti*****t as where i took the packet from it was clearly stacked with only the jumbo packs more then 5 of them, which clearly it was meant for them. however i did advise the cashier of the incident and he called Barry who was arrogant and naive about this whole situation who was not even able to answer the questions i had as he was mumbling especially when i asked him if the check the shelf to see that everything is in order he advised that customers mix up the products however in this case it was not that as it was neatly packed, i ended up having to pay the r189.99 however im was not happy about it and im extremely irate and also planing to put this on social media.
