Mr price online store is a ****

The online store is not efficient. I had placed an order and it was not going through and showing error messages. But on my banking app I had approved the transaction to go through. I eventually cancelled after two failed attempts. After 4 hours a transaction goes through that mr price has accepted my order yet the invoice shows that the payment is pending and I don’t have any correspondence from mr price about my order and delivery. I need that order to be cancelled and my money refunded but no response from them. Very bad service and bad online store
