advertise one thing, delivers another

So today I purcashed the bargain of a decade. R69 a kilo rump or sirlion .. but the quality was disgusting and the advertising WRONG! We hax guests over for supper and the meat we serves was so tough you could hardly bite through it. After supper we saw the add on tv. The ad clearly states the meat is 21 days matured but the packaging says 10 days. Also they had no rump available today ,only sirlion. What a watse of money!! The standards of the fruit and veg meat is up to no good!! I will never purchase meat from them again.
