Foshcini refusing to refund funds of online order

My daughter recently (September 2021) ordered a dress by Foshcini online, they informed her that her online purchase was successful. A week later they emailed her that they don’t have the dress at any of their stores and that she can claim a refund. She went to the store to claim her refund and then they informed her that they can’t give the refund as she has to speak to her bank to get the refund. 3 months later we are still struggling to get the refund and Foshcini seems reluctant to give the refund. I would not recommend to do online business with Foshcini.
