Bad experience with capitec bank

I was sending money to my brother only to find that he misprinted the number I was supposed to transfer money to. I made a transfer to the wrong person due to that. I phoned the customer helpline and I was told that there's nothing they can do since they can't get hold of the customer, they need his permission so they can take the out. I went to the branch the following day. They tried calling the customer but no luck. The money is showing from his account,yet they are telling me they can't reverse it because they can't get hold of him. I don't know why they can't help me because it seems like the customer has changed the number because everytime I am calling the number it goes through to voicemail. Seriously this is not far I really need to use my money. There should be an option that allows me to undo the transaction before a given time.
