Very dissapointing service at FNB to open a Foreign Currency account

I am very frustrated with the department of Currency Application within FOREX at FNB. I have been trying for weeks to understand the procedure to open an account of that type (I am a foreign national with a work permit wanting to open a Foreign Currency Account) and my email was bouncing between forex, non res, and other departments: no one seemed to know how to answer my queries. When FNB finally contacted me with the correct department (Currency Application-FOREX) I receive no updates, I call and the person supposed to open the account -Mercy Xaba- doesn't reply emails often, is unreachable by phone (Even her colleagues at the Non Res department can't reach her). I can't understand how everything relies in Mrs. Xaba and there is nobody else capable of helping me out. It is URGENT for me to open this account, I am really desesperate and it feels like there is nobody on the other side to assist me. I am very frustrated.
