Account closed without notification. Where is the money?

I am an international customer and do not use my account frequently. Recently when I did try to access my online banking, I was unable. I live in South Africa and given that BOA doesn't provide any alternative means to communicate other than phone, I was forced to do this. After waiting in the queue for some time, the agent informed that that my account had been closed? No notification from BOA and no idea where the money went? She only passed the buck and instructed me to call again to an alternative number - no email address available? How can BOA do this, and now it is my challenge to get in touch with them?
