Useless forex

Fnb advertises on their website that forex is open on Saturdays from 8 to 1, but when contacting them, no one is available. I find it hard to get how I can actually see the transaction on my account, yet we need a single person from fnb forex to release it. This now leaves me in a very difficult position as I was under the impression they will release it today. I have spoken to discovery bank and their process for this is automated. Hard to believe such a new bank is way ahead of fnb. Might be time for change after so many years with fnb.
