Banking Grievance

I open my credit card statement today - interest of $150 - almost double what it normally is...
I call to question (and complain) and the rude little so and so I get tells me - I can work out my own interest....
because it will take at least a couple of hours...
20 mins later when I have used their formula, it should be $80. - they have charged me a rate of over 35%!!!
When I ring dispute resolution and get a fax number to send through my workings - I ask about getting the entire interest balance removed for the month for my inconvenience.. and I was laughed at....
Looks like the NAB will be getting my fax in the morning and the Banking Ombudsman will be getting a call from me in the morning!!
ABSOLUTE DISGRACE NAB!!!!!!
