its Macquarie leasing

I rang back the number 0412 756 931, spoke with someone who hung up right away

When I called them back it said "the number you have called is disconnected". So guessing scam.

Caller: Scammer

Person with an accent claimed to be calling from macquarie leasing and wanted me to confirm my details. I've never contacted macquarie leasing before so strongly suspected this was a phishing attempt. Don't give our your details!

I called back number 0412 756 931 reached voice mail but did not say for what company.
