Money transferred to an incorrect Capitec account

On the 27th September 2017 I had money transferred to my Capitec acount and subsequent the money was transferred to an incorrect account. I went to Capitec bank to enquire that can't they reverse the payment and they said no and subsequently got told that they cannot get hold of the account holder that the funds went to as the phone is constantly on voicemail. They then told me to go find the person myself or his relatives to pass on the message that he must go to the bank urgently as the bank has froze his bank account. Capitec told me that they first need to inform the account holder that there is money that was deposited erroneously into his account. I was then only given his mobile number and nothing else to call him. I find this very ridiculous as what happens if I can't get hold of this person?
