Makro has not refunded cancelled order for 24 days (and counting)

I cancelled an order with Makro on 20/03/2023 (the same day on which the order was placed). I have written proof of the cancellation as well as reference numbers for my telephone conversations in this regard.

From their website I understood a refund could take up to 7 working days. When I phoned after 7 working days I was told it takes up to 14 working days and that they can see the refund as been made it will reflect by 12/04/2023 which will be 14 working days. I phoned yesterday (12/04/2023) to enquire why I have not been refunded and they told me they dont know the financial department will phone me before close of business on 14/04/2023. They once again **** to me and nobody phoned, it has now been 15 working days (24 days in total) that Makro would not refund my R6,798.

It would appear as if Makro is a lying retailer who deceives their customers and my only option to get my money back would be legal action as this comes down to *****.
