Unsatisfied Customer ( Exchange Policy)

Your Systems are not customer friendly. On Friday I went to Foschine The Grove to purchase a dress I found the store running buy 1 get 1 free. I needed 2 dresses but the was only 1 large on Black dress and no size on the white dress. They checked for me and said Menlyn has sizes of both dresses. I drove same time to Menlyn and when I got there the was only 1 white dress and they didn't have my size on black. I bought the 2 white dresses in Menlyn and ask a friend of mine to go ask if they can keep it aside for me so that I can drive back and exchange . He was told the store doesn't do set aside anymore. I asked him to buy the dress to secure the size and I will return the other one I bought in Menlyn and still get the deal. Tell me why today when I get to the store I'm told that I can't exchange buy 1 get 1 items if the items are not exactly the same. Mind you this is exactly the same dress different colour's. I went all out the get stock from 2 different stores only to be given money back instead of exchange. You would rather loose a sale than exchange items for your customers. I find this service pathetic after all efforts of securing the item from the same store and a different branch? I have been given money back instead of a dress that I wanted. Since I really needed that dress I had to pay for it again. And charged more. Please have a look at your policies to be customer friendly. You are a big retail store to have such petty processes
