Mr Price Online Purchase day Light *******

Good day Mr Price

I must say I'm REALLY disappointed by your Online shopping platform. I have made and an online purchase today 30/01/2022 at 11:20 on my Mr Price app. The transaction took me through the entire process until it asked me for a payment and I processed it with my bank debit card as usual. The payment went through /Off my bank however when the order was supposed to be processed or say successful it gave me an error message "Your transaction has been blocked" How do you block my transaction after taking my money. I have checked my bank account the transaction did not get reversed however the Mr Price App doesn't recognize the order. This is a day light ******* I need this to be resolved ASAP.
