I got a text from 'NAB AU' saying my credit card was approved and to call this number.

Not a bank - Aus banks don't use 1300 numbers

I think scam

Caller: Text message

Got an sms from 132265 which is the NABs phone number asking for me to call a 1300 160 809 number to query a transaction. The 1300 number is not a NAB number.

Caller: 1300 160 809

I got a text message from "N.A.B." saying they stopped a transaction and to please call them. There's no such transaction or attempted transaction on my account. This is likely a scam.

Text appears to be from 132265 and says to call this number
Pretty sure it's a scam

Message from NABAUS stating they stopped a payment and to call this number if I didn’t authorise it.
Obviously scammers texting as I don’t bank with NAB
