Where did the payment go?

I made a payment to my brother (who lives in Australia) in 2016. The first one went through so I made two subsequent payments. We never spoke about it as I believed he received it. During a visit to Aus this December, we spoke about it by pure chance. What he said shocked me. He never received the two subsequent payments! Thinking that I made a mistake I went back to my archived statements - but there it was - two payments of R150 000 each. Deducted from my account.

The logical response is to phone the bank. But after waiting on the line (paying international rates) I need help from someone higher up in ABSA to resolve this. Please help!
