Refund

I have made a wrong payment into a Capitec clients account from my banking app. I hVe phoned Capitec and they said i need to get permission from.the client to get the money back. The amount was R700.00 As at this tine we cannot get hold of the client so they told me it is a civil case and i need to go to the small claims court but this matter is to small for the small claims court. Should i not get the refund from the bank as they have all the details from the client as i cannot have it due to the popi act law. Please advice
