Permasters Boksburg false advertising

Their ad clearly states the dog food special is for the whole of May, while stocks last, however when we got there on 28 May, the managaer advised that it was only for 100 bags of food.

How is it possible that your ad states while stocks last, you have stock on your shelves, yet your manager tells me it is only for 100 bags which have sold out.

Your false advertising wasted my time and petrol as I drove 17km to buy this special.
