Bank keeps funds paid to a closed account.

On the 27 August 2022 I paid some funds into a Capitec Savings account for a family member. This was done from my Nedbank current account. Unfortunately the Capitec account had been closed for some time by the family member. So obviously the funds were not received by my family member. On phoning Capitec I was told the funds would bounce back within a couple of days. This never happened. I cannot get anyone at Capitec to show any interest in my problem. Once again a major financial institution refuses to do the right thing and return the money.
