NAB is National Australia Bank for those that keep saying a company called NAB, they call consistently if you haven't paid your credit card bill. I am guilty of this myself, but calling me and asking for an immediate payment wont help, if I had the money there and then I would have already paid it. I just don't answer unknown calls or calls I have googled and only found them to be scam numbers anyway.

I called back number (08) 8120 4485 spoke to a woman who said company name is NAB.
