Double money deduction from my bank account!

Good evening. I am writing this complaint due to the fact that I made a purchase on the Mr Price mobile app on 08/06/2021 and for some reason, my money was taken out of my bank account twice! Needless to say that I have called them and nothing has happened, I have been in store and I was told that I need to email the Mr Price help box. I have sent over 10 emails! I have posted and blasted them on Facebook twice and Mr Price still had absolutely no decency to get in touch with me. My total was R409.98 but that was taken out of my bank Acc twice. I am still waiting for my other R409.98. This is money that I cannot afford to lose out on. I find it completely disgusting that they don’t even have the decency to get in touch with me. I have been trying to get a hold of them for more than a month! When I went to the store, I was told to email them, and when I asked what other actions could be taken, I was told that they cannot refund me in store and that I have to just email until they respond. Well I AM SICK AND TIRED of emailing to a box that doesn’t respond. Mr Price - I WANT MY MONEY BACK!!!!!!
