Refuse to reverse my money

I accidentally transferred my money to the wrong cell number. After realizing my mistake I then called capitec call centre asking for their assistance, they advised that the persons phone was off but the money is not in the persons account as it is l frozen and that the reversal can not be done until the get permission from the recipient. This persons phone has BEEN off, it does seem to be working and I am still being refused MY MONEY! I called it immediately after making the transfer and to the day the number keeps on going directly to voicemail. The number does not work, meaning there is no one on the other end to give the permission for me to get MY money back!!! IM REALLY DISAPPOINTED IN THE SERVICE RECEIVED!!
