Nando's Meyersdal - Refund delay

On 23 March 2024 my wife attempted to order food on the Nando's app. The order was never completed but the funds taken from her account, after numerous phone calls with customer care and the store manager I was told to wait 3 days for reversal of funds which has not occurred. I called the store and the store manager (Nando's Meyersdal) requested I send proof of payment to her so that she can request a refund from the finance dept. , to date I have not received confirmation of receipt of my email even after requesting feedback. Can management please get back to me and refund the R452 back to my wife's account. I am very dissatisfied with the service received.
