FNB forex payments bouncing in FNB system

I made a forex payment. 2 days later the money came back into my account, at 1.5% less value! not even to mention the R800 costs to send the money overseas. The overseas recipient never received the deposit, thus it bounced somewhere in FNB system. I never even received any proof of payment from FNB, like my previous forex payments. What the hell is going on??! It is obvious that i bought the forex at buying rate, and then FNB paid it back at the selling rate.

Now for the "lovely" customer service: after speaking to FNB forex, they PROMISED to come back to me on the same day, that was 3 days ago... still waiting.
