Prestige Bank- you let me down

My Husband is in North Dakota. He booked a flights ticket on 19 April 2024 and the payment was unsuccessful, I called Flight centre to confirm the booking because the amount was debited on His Credit card. Only to find out Standard Bank blocked the payment. The funds is out of his Credit card and is now under Outstanding Authorisation. I called Card Division, I called Merchant, I called a Prestige Banker to assist because We need the funds to book a flight. They told me I need to wait 10 workings day for the funds to return to the Credit card. How must my husband wait for 10 days to book a Flight, this is urgent. I need this funds asap to book a flight. When it is sorted We will be moving to Discovery Bank. We didn’t want to move because I used to work for Standard bank and I understand the process, but this is disappointing!!!
