I want my refund back they must keep their meal...

On 2024-11-18 around 17:00 i sent my daughter to buy two(2) Big Macs meae her my bank card to pay. She then went straight to the self service kiosk as usual... She then inserted my bank card and the payment went through but she did not receive the slip. She went to an assistant nearby to let the person know what had happened. She then called me to enquire if the payment went through. I opened my Bank App and indeed the payment through. They refused to give her the meal o refund her rather .. i screenshot the transaction for her to show the personnel at the store still to no avail. I then instructed her to come back. I then went myself to the store and asked to speak to the manager. He said there is nothing he could do so i must just send my statement and they will forward to their finance office to deal with the matter. I am not happy as it shows that the payment went through.. i did send the statement to the email he provided but still no word. I am angry, i am ****ed cause this is not the first time i have encountered unsatisfactory service with them. They have poor service, even their food is not to standard.... I want my refund back and i will never ever buy from their branch anymore. I will inform friends,family and even colleagues not to buy from that branck ever again.
