It will all be OK (Score 1)

I can guarantee that all late fees incurred will be paid by NAB. This is a MAJOR news story here in Australia - the bad publicity is huge. If they reneg on any fees, there'll be blood in the water while the reporters circle.

I incurred some fees from a third party once when my main bank set my account up incorrectly. A simple letter was enough to get them to refund all of the fees. If they didn't, the banking ombudsman has the power to force them.
