Error deposit

I deposited money into a wrong bank account on the 27 of March. I paid money into CN Maluleke's account number: ***. I went to Standard Bank on Saturday to ask them to call this client and see if I cant get my money back they told me that they can't help me yet they have this client's details. I'm not saying Standard Bank should pay me back all I'm saying is that they must help me trace this client so that I can be able to get my money back. So what I need from Standard Bank is to help me trace this client since money was paid into her/His bank account which is ***.
