Missing Foreign Currency

Can I get help I've been stuck for a while. My school sent me money via SWIFT code to a friend's Discovery Bank account since I'm not a citizen and don't have an account. I saw Discovery Bank displaying forex adverts and thought they would accept foreign currency and convert it to ZAR but when my payment arrived from Bank of Cyprus into Discovery Bank via Swift code 4 weeks ago, the money was said to have been reverted back to Sender yet both UNICAF UNIVERSITY and BANK OF CYPRUS did not confirm the return of the money. The account owner logged a complaint which was not responded to at all until now
