Refund for online Purchase

On Monday - 11/04/2022, I placed an order on the Kfc app for delivery as I do not have electricty or water at home and i have 2 kids that were extremely hungry. After adding my banking details the amount was debited from my bank account and the app closed unexpectedly without giving me an order number. When i had logged back in tge order could not be tracked. I called Kfc Chatsworth Centre to track the order only to be told that they no longer offer delivery via the app. I cannot understand how delivery can be an option on the app if it isnt offered anymore. Never the less i afvised what had occured when i placed the order via the app and i was told to contact the customer care line. I have called over 20 times. Sent emails. To this date I have not received any response from KFC or a phone call to confirm refund. I was told funds will be automatically refunded within 24 hours. It's been 72 hours with no refund or response. The service I have experienced with KFC is despicable from both the chatsworth branch and the customer call center. I demand a refund immediately.
