Rude store management refuse to refund cash

Order# *** I went to Golden Walk and the manager, together with the supervisor Sanele and assistant Molebogeng ridiculed me when I wanted to return an item and insisted they refund in cash or back into my account because I paid with my bank card and it's within 30 days. They insisted I must get a voucher and made me out into a fool in front of other customers. I reached out for help on your Whatsapp channel and your consultant Precious said she can't help, that it's up to the store manager to decide if I can get a cash refund, she said and I quote "I cannot solve the store query." even though I asked her over and over again to confirm what the online returns policy is because I don't believe what the manager is doing to me is right. I left the store humiliated and heart broken, this is not treating customers fairly at all.
