Pathetic customer service!

As a regular Pick n Pay customer I am disgusted by the service I received today (10/03/2021). By the cashier,I was told that the nappies i was purchasing is higher than the price indicated on the shelf. So a supervisor said she will assist and walked away,she then walked passed AGAIN and said she is finding someone. I asked the cashier if I must go myself to get the barcode as there was a queue building and with a "hand signal" she showed the "i don't know" sign. The supervisor then came back and told me in a rude manner, "I can't see what you saw,why don't you come and show me." So I told her I'll show her and we walked to the aisle and there was infact TWO barcodes under the item. Instead of apologizing she started removing the price tags while I was waiting there and there was a queue. I received nothing but arrogance,I even told the cashier that she could of seen what I saw in the first place. I do understand that people make mistakes but what was the need for her rudeness. I do have the name of the Supervisor and if need be camera footages can be viewed. This occurred around 14:45,I was wearing a black t shirt and blue jeans unfortunately I don't remember the till number but it was about four tills away from the managers desk. With times that we are living in now, people should have more empathy and abit more respect,I rather shop at Checkers or any other store where customer service does come first!!!!!!!
