Avoid mr price online

I made an online purchase on Sunday the 2nd of August 2020. I'm guessing their app wasn't functioning well on that day because the card payments were bringing back errors, I then opted to use the other payment method available (instant eft via their app) the eft went through and R1390.90 was reserved out of my account later credited to mrp only to realise that the order didn't come through no purchase notification email and no update on the app of the order. I called mrp on Monday and was asked to send the proof of payment which I did, I called them and they didn't have it, waited an hour and called again and they confirmed receipt of the proof of payment. Tuesday 4th I called and spoke to a different person and she told me she couldn't see the proof of payment under my query I then emailed it again and she then forwarded to the finance department. I called again on Friday and nothing was sorted. Sunday evening received an email asking me to provide my name, email address & things ordered in order to get my refund, I rep**** to the email and today is Tuesday the 11th still no refund processed, called the call center and have been on hold for 13 minutes. I'm really frustrated by the service mrp is giving me after all it's not any fault of mine that the money is out of my account but no order going through. What other proof do you need before you refund me, my name is on the proof of payment yet someone emails asking for my name and email address yet they are communicating to me via my email, why the run around for something so simple. I'm fed up that's why I'm writing this review spent so much money calling their call center and not getting results.
