SPAR open sixpacks of milk as price is for loose boxes only

On 8 August 2022 we bought ten sixpacks milk as we do every month. The price on the shelf is R 28 for two boxes. When it scanned more at the till I told the lady that a sixpack should scan R 84. After consultation with her manager I was told that the reduced price is for loose boxes only, so I must take 60 loose boxes if I want the reduced price. I asked her if they were joking as I can just open one sixpack and then she can scan it and multiply it with 60. She said no, I have to replace the sixpacks and take loose boxes.

So I replaced the sixpacks and took loose boxes, there were only 40 odd boxes, so she called a guy over that stacked the shelves to open sixpacks and hand me the loose boxes. When I walked to the till, the guy stocking the shelves opened all the sixpacks that I returned to the pallet and stocked the shelves with it.

What is becoming of this country? Is there no more normal people out there? Where do they get their managers? Are they trained to be spiteful and stupid? Will buy my milk somewhere else in future, where the managers have a bit of common sense and decency.
