Cannot locate my money

On the 6th of March 2026, I used the tap feature on my phone to pay for an order at KFC. The order declined on their side but was completed on my end and I received an sms notification confirming that. @KFC refused to give me the order saying that the transaction was unsuccessful and that it would automatically reverse to my account. I called nedbank the following day and they said that the transaction didn’t appear on my list of transactions and they were waiting for KFC to claim the money if unclaimed the money would return back to my account within 7 days. The date today is the 16th neither of them are offering any direction. I have called Nedbank again as KFC is requesting a bank statement and I cannot provide it because the transaction doesn’t appear on my statement. So disappointed with Nedbank. I had hoped that this issue was going to be resolved efficiently but it seems I can’t trust them with my money.
