Payment reversal

I would like to receive a call back from Capitec explaining this so called process that doesnt make sense, I mistakenly send money to an account, tried calling that person to send it back the number does not exist and you cant reverse it how when im the one who sent it and it reflects as a transaction in my account, you say I should send a request to that person how so I know if that person is still alive seeing as their number does not exist, spoke to an agent by the name of Thokozani who asked me stupid question knowing in the end its not possible to reverse why wasnt he straight with me from the on set, I requested Capitec to send me back my money. Im soo mad
