Scam message allegedly from NAB

Asked about Updating NAB account details, do not have a NAB account.

Caller: I got multiple text

Multiple text saying it was NAB stating I needed to update my details with link.. I don’t have NAB account

SCAM. Saying message from NAB but we’re not even with NAB. Replied and they replied very unprofessionally.

just got a text from this number telling me I need to update my details with the NAB - calling BS on this...

NAB please go to link to update your details
Don’t have an NAB account

Total scam.

I have never been a NAB bank and got this message from this number 0457 674 549:

important information from NAB. for your security, you will be unable to use NAB services bla bla bla click here: https://ibnab.mo/?update or calling NAB on 13 22 65

Supposedly Westpac saying update details. Treating as a scam.

Text message Said my westpac Acc needed updating
