Forex payment to wrong account HELP URGENTLY PLEASE

Hi FNB,

We have made a German Forex payment of EUR5,000 to the wrong account. The money was paid to FNB account number ********** 134 instead of to the below:

First National Bank Account number : ********** 6334 Branch code : 255005 Branch name : FNB Corporate Banking Reference : ********** 0069 Swift: FIRNZAJJ***

This payment has been released by FNB unfortunately. Please URGENTLY can your Forex department phone us and help us to find the payment and route it to the correct FNB account number. Your reversals department cannot help us. They say that we need your Forex department.
