Double Charged with no refund or an apology

I was at Ackermans in Vincent Park on Friday the 20th October 2023 time 13:55 I bought two ladies shortsand a toddler dress. I was served by a lady named Laurika Kroutz I was using my Ackermans account card. She charged me for two dresses but I bought one toddler dress. I called them Saturday to tell them I won't be able to come as I have an infant who is not well at the moment can I send my daughter with my ID and Ackermans card with the clothes I bought so that they refund the credit back to the card. I was told I can send my daughter. When I did on Sunday today the 22nd she was told to go back I have to come. Why did Laurika agreed to me sending my daughter to send her back again and made remarks asking about my whereabouts where as I explained. They did the mistake of double charging me. There was no apology I now have to go back again at my expense over a mistake they made?
