Nedbank has world-class customer service....not.

Hi there - I've recently switched banks andI really, really want to update my home loan debit order details with Nedbank and have used more than 45mins worth of airtime. Now my airtime is done and I have not yet completed the task because the customer service is up to ****. Have filled in the call me back form on the site too and no response....this is pretty crazy. Can you please get someone to phone me???!!!!
