R1600 wrongly transferred into another Capitec client

Cellphone banking my husband was trying to transfer money to my account and mixed up the numbers 10 minutes later after realizing he made a mistake he was at a branch to try and retrieve he was told the money is gone surely they can freeze the person"s account until they reverse the amount we were told they cant do anything and gave us the name and surname of the person R1600 is a lot of money for the bank to say they cant be held responsible, I will not stop until the funds are back into my husband's account.and someone must be held responsible it was a mistake and they need to find ways of helping their prospective clients.
