POOR SERVICE ON THE BANK NOT THE AGENT

I was making a payment to another Capitec client using their cellphone number. Now I immediately realized after payment was successful that the number is incorrect. I contacted Capitec and am being advised that they cannot reverse the payment without the consent from the person the money went to. Mind you I made the payment, i am enough proof that the money came from me. What more proof do they need to take back the money from their client. Money came from my account to other party, so am telling them which account the money was supposed to go and yet they still want me to await conformation, what confirmation??
