I just had a baby and her great granny bought her an outfit online due to covid. I went to exchange the size and they wouldn't let me exchange , I even wanted to spend additional money but they said the system couldn't because I didn't have the original card, but it's not my card and my 80 y old gran doesn't go to shops during covid. I had all proof of payments and all. I am disgusted that in a shop where one is spending so much and will pay more they cannot make plans due to these difficult covid times. This is unacceptable and I will never get anything from naartjie again. naartjie has greatly disappointed and I would recommend you to spend your money at shops with real standards.
