The SneakerDon Poor Delivery and Service

I had purchased a pair of sneakers from The SneakerDon in Cape Town on 4 November 2022. I was asked to do an immediate payment and the sneakers would be posted to me via Postnet which I also paid for. I have not received the sneakers and my calls and messages to their number is ignored. Please can I receive some help as I have been left so frustrated with trying to follow up for a month now. The SneakerDon contact number is ***.
