TFG Online / Foshini

I placed my order on Monday 30th for 5 items and received multiple deliveries which I did not have a problem. Thursday I receive my last delivery for a dress from Foshini and I received a T-shirt from sportscene. I called the online store to advise them of the error and was told to return to a Foshini store. I went to the Foshini canal walk, waited over 30 minutes while they were trying to sort out what to do about the error. I was told they can't accept a sportscene item. I left Foshini with the incorrect parcel and no dress. I'm disappointed, when I placed the order, I did not receive any feedback that the item was out of stock, then to go through so much hassle.
