Didn't answer this number and looked here to find this :)

Keeps calling me asking where I keep the dank memes.
Wait until they find out I only have rare pepes!!!

I have just put my complaint threw and threatened them with the federal privacy commissioner lets see if they do anything

These spam calls are getting ridiculous... every day.. another bank. I'm so over it. not a NAB customer either..........

Received a couple of calls from this number after 7 pm. Hate it. Blocked it now.

he called just after 5pm and asked about bank details for N,A,B.my wife refused to speak to him

Caller: NAB

Seems to be NAB call centre. Nothing but a nuisance. Blocked the number now.

This number just keeps calling me. In the last two days this number rang five times!! They don't leave a message, but one call went through to voicemail. They didn't say anything but it sounded like a call centre in the background. I am sick of feeling harassed!!
I have just blocked the number :)

And 2 years later, they are still doing it. NAB researchers.
This week I got three calls. First I was busy and asked to call later, the second call I said I'm not interested and don't want to participate in a survey and yet they called again-I didn't answer.

got 10 calls
at school
freaked me out so bad. ):C

No idea who just called me, it's 7:30pm and I did not pick up. Comments say it's from NAB and I am a nab customer. If it really is them, I think it's very unprofessional calling this late.

Has called several times over the last week. I never call back an unknown number as they latch your call and use it to call overseas and you get lumbered with the bill. There must be some software that permits them to do this. Anyway, they don't want you to answer - they want you to call them back. So Don't.

Scammers posing as NAB

They are not NAB, likely be a scammer after your money. Don't bother answering.

It's actually not NAB. And if you try calling the number back it doesn't go through. NAB say it's not their number.
