Extremely Bad Customer service

Yesterday on 20th October 2022 went to Pick n pay liquor Meadowpoint in Soweto around 15:00 when i got there i asked if the special they had on Bernini blush is still on i was then told that it got finished on Monday ok i then went to fridge to get a 6 pack of Bernini blush which was priced R89 I then took to the till to make a payment when i got to the till it scanned R105 i told the cashier abt the price i saw on the fridge & she told me that at Pick n pay they use bar codes i then started telling her about my consumer rights she then told me that she can call her manager she asked a manager while the manager was standing by the door without coming to us then they spoke in their Tsonga language the manager said i must show him the price on the fridge which i did he then said it's wrong prices & removed the price in front of me while making a noise i started making noise too about him not doing a proper job while he kept on saying to me i must go back to school as I'm not educated he also asked if this is what we do at our company this guys was raising his voice at me loudly in front of customer & his team members, you Pick n pay if this the kind of behavior you allow from your management i pity the staff as this is not how you treat your customers, firstly he violeted me as a human being but worse as a a consumer I'm still questioning if his really a manager there.
