I want my refund for sneakers ordered in December 2022 and never delivered

I ordered a pair of sneakers from them for R1600 on 23 December 2022 and to this day, I have not heard from them. I have been following up with them on a number provided 071 062 7205 and they have not bothered to provide updates or anything. I would like my money back, no longer interested in the sneakers.
