Capitec not reversing transfer paid into closed account

On 02/12/2025 I transferred money from my Capitec Bank account to my Old Mutual Bidvest account. Old Mutual was busy moving their Bidvest customers over to OM Bank. When I sod the transfer my Bidvest account was already closed. Once I realize that the account eas closed I immediately went to OM bank and inform them about this. They phoned Bidvest who confirmed that the account was closed and the money was returned to Capitec. I then went to Capitec Meyerton branch and they told me that it will be reversed within 48 hours. Up to now, 11 days later, still nothing. This morning, 13/12/2025 I again went to Capitec Meyerton branch and then the consultant registered a complain and gave me a ref no. She then told me it will take between 7 and 30 days to do the investigation to see where the money is. How can Capitec take this long. The money is in their suspense account and they get the interest on it. How can they tell me the money was paid into a closed account. Do they think we are stupid? Poor, poor service.
