Mistaken Transfer

On the 18th Feb 2022. I mistakenly sent money into a wrong cell number. when I picked it up I then phone the bank on the very same day. They gave a reference number but never called me. I followed up with them but with no desired results. I was told by the bank that they have spoken to the person and he had refused them access to his account and as a result there is nothing they can do but its now a civil matter I must go to the small claims court but they haven't provided me with the details of that person and when I go to springs branch, I am told I must do an an affidavit. I have since not received any proper information and haven't received my money either. I am just left alone and to decide on my own.
