Stop transferring me from one agent to the next!

I am trying to get a telephonic quote from Nedbank to buy foreign currency. After being transferred 11 times and holding on for almost 20 minutes, I gave up. No one seems to know what's going on - while I'm still busy trying to tell them what I need to find out from them, I'm already being transferred to another person. I just want to know what procedure I must follow and find out what their fees and commissions are! Very bad service. Nedbank should jack up their call centre service.
