Process my refund please

I usually buy in-store but the week of Black Friday (25 November 2022) I wasn't feeling well so I purchased a baby wash basin online, paid R335 in total including delivery. I made the purchase on Sunday the 27th. On Monday I got a call that they wouldn't be able to deliver the item as it wasn't in stock anywhere (Dischem and Baby City) so they'd need to refund me. I agreed since there was no other choice. Later that day Dischem Sea Point called and said they actually found one in white at Baby City and would be delivered after all. I was happy about this. Then they called and said again they couldn't give me that one and were going ahead with the refund. Again I said ok. I still have not received the refund (today is the 11 of December). I was at Dischem Sea Point about 4 days ago to follow up on the refund as no one was helping me telephonically, I was told the refund had been processed on the 30th of November already. It's supposed to be a reversal on my card so I don't understand why this is happening. Also the basin is listed as in stock online just at R200 extra and I'm guessing this is why they said it's out of stock. The least they can do is give me my money back. That's all I'm asking.
