False adverti*****t

I received the worse treatment at Clicks Canal work. The huggies Gold nappies were advertised ar R29.99 a pack, when i got to the till i was accused of lying and that i took the picture of the advert at another store they sales assist then went to call the manager we was so rude she claimed that it’s a mistake not once did they appologize for accusing me of lying and also refused to give it at that price advertised and stated that i can go complain online. When i told her that as a consumer i have the right to pay the price advertised in store she did not care and was disrespectful
