Free bag with Perfume

Hello.<br> <br> My husband bought me an expensive perfume on Valentines Day from Foschini.The sale of the Alien Perfume was suppose to come with a free bag.We did not receive the bag as they stated they had no stock of it.They took our number and promised to call as soon as the stock arrives<br> We are now is May and still to date have not received the bag or a call <br> I have been twice to the store and they keep saying that the rep has still not brought the bag.Why does it take 3 months to get stock of something.<br> Dont have promotions if you do not have stock and can not meet the demands
