DISGUSTING CUSTOMER SERVICE FROM MRP

I made an online purchase via the app on my phone on the 10/06/2021and was taken from the order page to the payment page at which stage I did an OZOW payment. The money was taken off my account but the order number didn't generate. I logged in and out of the app and the items are still sitting in "my bag" on the app till today, but the money was deducted off my bank account. I have been endlessly trying since then to get Mr Price to refund me my money but they will not. I provided proof of payment and every day call at least 3-4 times and speak to the customer service agent but each time I get told they await feedback from their finance department, I provided a screenshot from my internet banking and the sms's which show that a beneficiary was created for mr price and it also shows the payment amount, the account number for mr price as well but I get told this morning that they cannot pick up that transaction on mr price side--- surely they can go through their bank statement and find this amount and verify with the proof I provided?? I want my refund MR Price or I will use alternate other social media assistance as next method of communication to expose this incompetency due to the MR Price app failing.
