Frustrating Failed online shopping experience

I am an existing online customer who saved my payment card details on the system. I placed an order and selected the card to make payment. The order was received and I was issued with an order number. The next day the order was canceled by Mr Price. I reordered the items 3 times following the payment instructions. Keep being told by the system the order is confirmed but nothing happens.

The WhatsApp number, complaint email address and contact centre are not responsive. It's a frustrating online shopping experience.
