Unacceptable Treatment

I am very much disappointed by woolworths Sandton Mall. I must say I did not expect that kind of treatment from them, woolies have been my best best retail store and never could thought that one day such an experience will happen. I bought 3 items from them on the 24/12/17 for my sister and it happens that she doesn’t like the type of clothes I have bought her. On Christmas Day the 25th she went and returned one item from the 3 I have bought and she was gladly assistant not knowing that the other 2 items she left also doesn’t fit her properly as she did not fit all 3 before she went back to the store. Today after work I had to take back the clothes and bare in mind they are still clean with their pricing tags but the only problem was that I did not have the slip with me due to the fact that my sister left it with the cashier who was assisting her on the 25th when she came to exchange for something else. So the lady who was assisting me this evening is telling me that she is going to refund me on a gift card as I no longer have the original slip and I am saying to her no I don’t want a gift card course the items I have bought were on sale to start with and the sizes are no longer there I would have done a exchange, I am telling her I used my woolies points card and my cheque card if she needs to confirm if I really those items were bought by myself. She refused I then asked her since one signs and even include a telephone number when doing exchanges why can’t she goes back to her records for the 25th where they attach the slips so I can check the slip for myself since she is unable to be helpful. With my points card it is only registered with my identification number, mobile number and so on it highly impossible that she can pick up a wrong person. Another thing which has no logic to me whatsoever is that alright I agree to gift card, does that mean now I must purchase something worth the gift card amount in store then get original slip and again go back to customer service to return staff that I had just purchased in order to get my refund not a gift card, just because of slip and she could trace me by using my points card to see if I did purchase these items or not. I think you guys needs to find some way or means of coming up with a better way of doing this refund thing course if one has a card with you clearly it must be easy to trace rather than I purchase then go return them again for a refund. I had never come across such behavior especially from my own woolies store Sandton Mall?
