deopsited money into wrong account.

Today on the 29th of July, I deposited R2000.00 into the wrong account through cell phone number to a Capitec client. I immediately went to bank so that they can reverse the transaction and put money back into my account. What they told me was, they are not allowed to reverse it without the client approval. The wrong client could not be found and they said if they cannot find the client, within 3-5 working days, the money will be released to the client, not back into my account. How unfair is that? I called their clientcare, they told me the same story, how can they do that to their clients, no one can go to bank and claim that the money was deposited in the wrong account. Where is client protection??? why should they get permission from someone who does not even expect any money into her/his account?

I am very sad and upset by their service.
