Reversal of deposited amount to the wrong number

good day

Yesterday the 11/07/2022, my sister sent me money on her Capitec app, she punched in 1 number incorrectly from the cell number she was sending too. the money was paid to the wrong account. She went to the branch to try and reverse it with all the proof on her handset, but she was told they still need to call that person he wrongly sent to before they can reverse it.

Besides that l am stranded as l need that amount but when they call that numbe5r it goes to voicemail and she was told she has to wait until they get hold of that person before they can reverse it. what if that person changed the number or anything else and they never get hold of them. She sent the money and on her app is that not enough. we needed the money so badly.

Some company policies are really not warm.
