Woolworths Braai Day Reward - false advertsing

Thank you Woolworths for sending me a wonderful voucher to be used for braai day. Spend R450 on braai meat, bread, salad, etc. and get a whopping R75 off. So buy a lamb pack with some nice chops. rib and neck in it, beef burger patties and a garlic butter bread (this all exceeding R450), and then also including some other meat items , chips and cooldrinks totaling over R750. Just to have the cashier and manager to tell me that the lamb pack is not classified as braai meat. They could not explain to me why. I decided to cancel the transaction on the spot and left the shop very unhappy. This is false advertising to attract people to your shop and then tell the customer that even though you selling lamb chops and ribs that you cannot braai it and therefore it does not count towards your rewards. So take your rewards , and my future business and shove it. I will be shopping elsewhere.
