Terrible service. No communication. My money is gone.

I have been with FNB for my whole life. My parents are with them, my grandfather was with them. I have my home loan with them, I have everything with them.

On the 18th of March I transferred money into my Global account. The money disappeared out of my account and never showed up in the global account. After 8 days I contacted them and was passed from department to department ever since. I've gone banker -> forex desk -> banker -> forex desk -> dormant holds -> banker etc. My contact who was responding to me went on leave before anything was resolved. I have spent R100s of rands in airtime being left on hold. My money is still gone, I am not earning interest on it, it does not exist as far as I can see. No one can help me or wants to help me and I don't want to be a part of this bank anymore. Terrible.
