Please kindly assist me because I need answers

So yesterday I made a mistake mistakenly deposited money into a wrong account no. Which is one of the people I have paid before because they were my beneficiary but when I foned capitec i was told they needed permission from that particular person to reverse my money and they couldn't even tell the person who is looking for their money because they cannot disclose that information even though I had given them the right to say who iam.... Secondly they cannot even freeze the account until proper investigations are done so that I can get my money back it's not her money it's my money and they can see the transaction made from my app..... And it's not like they have never made a mistake by doing transactions on people's accounts what permission did they require to put back that cash on their accounts?
