False Advertising

Shopping at Woolworths I am always on the look out to shop Vitality products. Today was no different, just to arrive at the till, once paid, I notice that the Guava halves in fruit juice was not marked as VIT on the till slip. I checked the shelf - wow to my surprise the price and the Vitality logo appears on the shelf price. No I get penalized for shopping healthy due to the fault of Woolworths. I do wonder how many other customers this happened and might of not even noticed. The type of false advertising done by Woolworthts and the Woolworths get away with it! Wonder what the Advertising Standards Authority of South Africa (ASA) would say?
