Incorrect pricing and bad attitude

I bought cheese at Checkers Raslouw this afternoon. The shelf price was 59.99 and was said to be on special. The till price was 84.99. Luckily i saw that and i showed the cashier who inturn showed her supervisor. 1. The supervisor was not interested at all, showed me printed specials that the cheese was not on special. I then asked for the manager who also came with a bad attitude. They eventually refunded my 25 bucks. This was not happening for the first time at that store and it was now the third time in as many months i paid the price that was not advertised on the shelf. Unfortunately i only managed to see on 3 occations. Just wondering which of the items on my weekly trolley are actually tilled at the advertised price. No more Checkers Raslouw for me.
