Wrong products on the shelves

I activated their new Xtra savings card and with my first use I did a good saving on the available products, until. I went to a checkers yesterday and after taking one of the Xtra savings products, getting to the till I was told that the packers packed the wrong product on the shelve. Well, I was not in the mood for arguing but didnt take the product. Another product I wanted to buy, also again was incorrectly packed on the shelve. No quality checks in place and will rather shop at PicknPay
