I went to a NAB ATM to withdraw $800 in cash using my UK debit card (I have most funds going there now as I'm no longer Australia based).
It was making the noise like it wanted to disperse the funds but then an error came up with the screen saying "Machine Error" with no money being dispersed.
When I checked my online balance, the $800 was taken out.
I called NAB and got the run around for a bit since no one really knew what's suppose to happen or how to handle it. Eventually I got passed off to someone in the credit cards department and they said that if the money is taken out already, then the ATM won't return the funds. Since they don't "keep" any details, I've got to go to my UK bank, inform them and the UK bank has to initiate the request to get the funds.
Has anyone else had this happen?
Yes normally you contact your bank and they will contact NAB and if they find the discrepancy when the machine is balanced they should credit you. I guess it will be the same even though it's an overseas bank.
