Card transaction faulty

Please assit on the 16th April 2022 Mid Afternoon around 16:20 . Purchased 2 items Brightening Mask Vitamin c and a snack total amount: 64.98. Please note I had like 82.00 in my account as before swapping I made sure I had money . I swapped the items when I was done, the cashier said something is wrong and asked if I got a message, told him no . Then another lady came through and then I had to retry again then CARD DECLINED for insufficient funds.

Later that day , I checked on my capitec app and the amount of R64.98 went through, it also shows the insufficient declined amount. I called the call Centre no response.

Please advice how I can be assited in getting my refund
