Item not of specification as advertised

Recently I was shopping for a new usb memory storage. I was on the point of ordering when I realised the Item that will be shipped is not the Item advertised but rather an Item of much lower specification.<br> <br> I Was looking at the Sandisk Ultra Fit 64Gb. It is clearly presented in the picture as a USB 3.0 64Gb. Just before I finalised my order I realised the item that will in fact be shipped is the 16GB and not the 64Gb item.<br> I need 3 USB 3.0 memory sticks for the price advertised. <br> <br> I Phoned a while ago and even a staff member I spoke to at Kalahari was convinced that the item is 64Gb until someone in IT told her otherwise. She never retuned my call after I expressed my dissatisfaction and I am still waiting for this to be resolved. <br> I see that after two weeks the item is still advertised like that so please help me to place my order so the correct item can be shipped to me A.S.A.P.
