Delayed refund

I've posted already. I've returned a takkies on the 9th paid from my debit card. The refund I was told cannot be cash, and cannot be refunded to my debit card and I needed a credit card. I used my husband's. This transaction was done on the 9th July 2022. A gentleman called on the 18th to follow up as a result of my initial post. To date, my husband hasn't received his money. Where is the customer service in this scenario.
