Free gift not received

Last week I ordered Jennifer 4 piece luggage set which was advertised on their Sept catalogue as Buy 1 and get 1Free Jennifer 4 piece brown luggage set .Luggage set was delivered without FREE gift ,I called them on Monday the 21.09.2015 and I was told to wait for 48hours .I followed up on Friday the 25.09.2015 another person told me to wait for deliver within 2 weeks ,same day in the afternoon I received a call from Homechoice telling me that I shall not received the gift as there's are out of stock ,so I asked her why did they not state that in they advert so she me you can see it when you order online .I feel that Homechoice is fooling the people with their false advert.It was my first time I ordered something from them and it is the last time because of their bad service.
