The message sent by this number is supposed to be from the ANZ bank, given comments below, I can only assume this is an attempted scam.

Caller: 0488 728 596

Definitely a scam, received 3 messages in ten minutes saying this:
“Your $***** transaction was declined as you would've gone over your spending cap.”
3 Times with different amount..
And I haven’t done any transaction.
Normally I would receive an email from the bank notify me.
Scam
