ZERO service from Nedbank

I am leaving the country in two months' time. I was told to sign an indemnity form so that if I wanted to transfer my funds to overseas account, I can just email/fax the form to the bank. I went into the bank on Saturday especially to sign the indemnity form. I needed to send money overseas today and tested out the service. Out of the 5 email addresses that I was provided with (the teller said just email them all so that if one is busy, someone can help me). 2 of the 5 is full, the other three didn't even bother to respond. I sent the email before 12 noon. After 30 min, I didn't get a response and 2 of them being full, I forward the email to another teller that helped me a few months ago on a separate issue. Again, no response. At 3PM, I started calling the bank. Asked to speak to the FX desk, was told the main dealer was sick, but can forward to Mary-Jane, which I did. Call her at least 5 times after that, and for the past 90 minutes, the response was that she is with a client. I ask to speak to the branch manager, Nicholas answer the phone. This was just after 3, and as it turns out, Nicholas wasn't the manager. and never call me back. 4:30, I was told manager left for the day.
