Fresh stop Bryanston Main road- Robbing people for R4.50 for bread

Good day, Please note on the 20th of February i went to fresh stop at Bryanston Main road Caltex garage. I went to the bread isle and saw a loaf of Albany superior white bread 700g on special for R17.49 as advertised on the shelf( I am in possession of pictures), The advert says "THIS DEAL IS VALID: WED 2nd - SUN 27 FEB 2022.".

When i get to the till and after it being scanned the rude cashier on duty says its R21.99 , So i then told him but on the shelf its advertised for R17.49 & proceeded to show him, He then tells me he does not know anything about it and he believes its been put up 3 hours early whilst he was not on shift and its not being updated on the system. "This is now 18 days after the advertised special came into active play". So anyways he could not do anything about it. So i then paid for it. He told me they would fix it on the same day later.

On the 22nd Of February i am back in the fresh stop store and buy a loaf of bread again and when at the till it still shows at R21.99 which i paid for again, when i asked him why has it not been rectified since the two days before ive been here and complained, 'he says he did take up with his management and they are not interested in fixing it" So he cannot do anything about it and he is sick and tired i must pay full price.

So my argument is if they selling 200 loaves of bread a day and robbing people of R4.50 , That's R900 a day that they are pocketing.

I have pictures and my slip to prove it.
