Rude and arrogant management

I was at truworths promenade mall on friday and wanted to purchase a few ring and earring sets which was on sale for R35, when i came to the till the cashier told me the stuff is scanning the normal price of R120 and its not on sale i then told the cashier that the customer pays the price on the item which was a red stickers R35, i then asked her to call the manager, she then went to the managers office which is right by the tills she could see me and i could see her she then didnt bother to come out and sent the cashier out to tell me the items are not for sale i then sent the cashier back to call her then she came out looking annoyed i then told her doesnt the customer pay the price the customer sees she then told me rudely in an arrogant tone of voice that its human error and that people make mistakes infront of all the other people in the line, i then told her human error is when you put a wrong price on 1 item but all of those ring sets were at the sale rack all with red sale stickers of R35 i then told her to come look and showed her, she then told one of the staff members to remove all the sale stickers and put it all back on the other rack with the normal priced jewelry and walked away, this doesnt happen at your canal walk and waterfront stores just because its a mitchells plain store and mitchells plain customers your manager thinks she can treat customers the way she did and belittle me infront of all the customers waiting in the line everyone was looking at me i really felt like jumping over that counter but i just kept my composure and left the store
