I am deeply disappointed with Miladys in South Coast Mall

I am deeply disappointed with Miladys in South Coast Mall. My aunts sister-in-law bought her a dress, which was too big. A few days later, my aunt tried to exchange it while still new and tagged. The staff refused, citing no slip, despite her explaining it was a gift she then obtained the slip and returned. They then said the exchange couldn’t happen because it was bought on an account, requiring the card—despite just needing a size change. My aunt contacted her sister-in-law for details and returned to be told the dress was purchased at Eastgate JHB, so they couldn’t assist. She was emotionally distressed, even crying in the store after multiple trips. Only on the fourth attempt did another family member succeed in getting the exchange. I find this level of unhelpfulness unacceptable and deeply disappointing
