Private Clients service is a joke

I have been trying to get hold of the Private client Home Loan department for 2 DAYS!!!!! No one is answering the phone and when i finally got through on day 2 the person said i should hold on so she can process my debit order date change. I kept on waiting for 6 minutes where after i hanged up! This is absolutely absurd! If my home loan goes of an the date with no money in my account FNB will reverse any and all penalties i received for failed debit orders.
