FALSE ADVERTISING AND RUDE EMPLOYEE

I recently went in to the foschini at the boardwalk to purchase a promotional item that was advertised on the website and the beauty magazine.I went in to the store to make a purchase and was dealt with by a rude and ill mannered employee, she told me the promotion ended last month. i assured her i recently saw it online. She was very rude and unhelpful, after about 45 minustes of me waiting for her to assit she finally comes back and informs me it is a box set on promotion. She said she wont be able to assist me with what i require due to what i require being loose items. <br> I further went to ask when she will recieve stock and again very rudely she says no one has stock.<br> Why is foschini advertising for things they do not have.
