Reversal of Fund into wrong account

This is my forth review regards the reversing funds of a deposit into a wrong account? All avenues that I tried ran into a dead end, I really don't know what to do except writing of a few thousand rand due to red tape. Capitec told me they can not get hold of the account holder, therefore no reversal can be done without his permission. Nobody can reach this man, maybe he is no longer with us?? Capitec insist going to the SAPD to open a case, in Cape Town SAPD refuse to open a case of "******** self enrichment", they do not do cases like that?? dead end? I try to get the process to follow the small claims court route from Vredenburg Magistrates office Western Cape, the lady told me that I should have checked the account number before making the deposit, and she is sorry for my loss, they do not do cases like this and I have to accept my loss??? another dead end. The banks response," Sorry Sir we can do nothing for you???" another dead end?? I don't know what to do? Any body any suggestions? I even try to contact the account holder with a photo on FaceBook, no luck?
