Advertising goods that haven't reached the shop

On the 16th of December I received a promotional pamphlet with my local newspaper advertising an XBOX 360 play and charge kit. I then went the following day (17th) to purchase this item. Upon my arrival I asked the lady behind the counter (who wasn't too keen to help me, I might add) if they had the item in stock. She then responded lazily that she will ask someone to help me and returned to her chair and continued to read her newspaper, how professional that looks. Eventually a gentleman arrived who was very helpful and told me that they hadn't in fact received the stock as yet, he then phoned another branch for me and they, also, haven't even received their stock yet. The promotion on the pamphlet says 14th December-24th of December. Wow, Pick 'n Pay you have really out done yourselves, advertising goods that haven't even reached the stores. I am very disappointed seeing that myself and family have been supporting you for many years now. You cannot, especially during the festive season make such mistakes. You are angering a lot of customers.
