Bad service

I went to boxers kaalfontein supermarket early inthe morning around 8: 30 firstly i want to saying well done to the management team the store was very clean and well housekeeping. What disappointed me was when i got to the till point and the cashier tell that the 5kg chicken that is on promoting of R169 is not on that price on promoting yet i must come back later they still try to fix That, of me was a nonsense bcz I use my time and taxi to come to buy that chicken bcz is on sale and now u telling me to come back LATER 😠😠😠😠i feel like they are not taking customers serious because that is nonsense...
