Refund

I went in store to make a purchase with my bank card on 22/10/22, the payment didn’t go through as they had load shedding. I then made a cash payment and left the store. On Monday morning 24/10/22 at 3:00am, the money was debited from my account. I have went in store, the manager escalated and was told I would be refunded back into my bank account. Nothing! I have emailed, I have sent them messages on social media, no response, no follow up.
