Double Charged (R753.51×2)

I am very disappointed by PNA, on the. 17th of January 2024, I went there to buy my stationary and my card wasn't eorking on their machine so I used a scan to pay method as the Cashier advised me to do so. I made the payment and they didn't recieve the payment on their side but went through on my side. I was told to wait for a few minutes it would be back (R753.51), I was for over an hour and then I decided to visit the Capitec branch. I explained everything to the Capitec Assistant and then she told me my money would be back within 2 hours. I couldn't wait for 2 hours to get my stuff out of PNA so I decided to go to an ATM and Withdrew R800.00 so I could pay cash for my stuff. I did that and went home with my stuff paid for and with an hour my money was back. Suddenly on the 19th of January (R753.51) was debited from my account referenced PNA Stationers, I went to the Branch and told them I need my money back and they said they're going to wait for their accounts manager to do a refund, I waited until the 23rd and then I called the PNA Head Office and reported the matter and they told me they would call, however today its the 25th and I haven't recieved any call, I really need my money back. I have all the receipts and proof with me.
