FNB Global Payments problem

I'm currently in the UK and urgently need to transfer money from SA to my UK bank account via my Global Account and the App is not allowing me to process the transaction. This seems like a system or Banking App problem, as there is no place for me to correct the SWIFT/BIC code. I chatted with an agent Maanda on the Banking Chat service on Friday night 9.15pm UK time, who told me to contact the Forex department, which will only reopen on Monday at 8am SA time. Despite my informing the agent that this is not a Forex issue, I was given an apology of the inconvenience and no alternate help was offered. As a Private Wealth client, this is absolutely unacceptable that I have to be without money for 2-3 days and my FNB bank that I have banked with for more than 12 years cannot even look at the system error, and merely pass me on to another department just because the agent is not understanding the nature of the problem. Why does FNB even bother with a SecureChat option for Private clients, or any other client for that matter? Can anybody in FNB prove me wrong and provide help with a simple banking transaction within 24 hours?
