Delayed refund

I am so very disappointed. I ordered a bracelet online for R2923 on 17/08/21. It was a gift for a friend. I later realised that it would be too large for her tiny wrist and wanted to cancel the order but it was too late to do so. The order was delivered. I did not even open the package and took it back immediately to the NWJ store at Cresta Mall for a refund (which is what the website tells one to do for a refund) on 19/08/21. I was told by Patricia and by the manager telephonically to fill out a form with my banking details which would be sent to head office for a refund. Patricia opened the parcel and confirmed that it would be refunded the following week. It is now over two weeks later. I have phoned the store several times, I have emailed NWJ, Patricia keeps telling me the money will reflect on the day I call, but it hasn't reflected. I am very disappointed because I am a good customer of NWJ and I really expected better. It is a large amount of money and I can't keep running after it as I too am busy, and I still would like to buy my friend jewellery as a gift. The website is not clear and the process is unacceptable. The order number is #***. Please can somebody sort this out. I do not like to complain but I feel like I am being forced to do so due to lack of action.
