I called back the number (02) 9137 2701 and reached vm that did not mention the company name

Asking financial information. Saying they can save you money on tax. Feels like a different strategy to get you to buy some kind of investment. Definitely unsolicited sales or possibly fraudulent.

Constantly calling and not leaving any message!

Called and when I answered the call it was disconnected

Called me two times today.

Got a call and they said they were from the government looking to help households save money on tax. She then asked me how much I earned and whether I owned my property. I'm sure if it were the "government" of Australia they'd know. Scammers.

This number called and hung up

Potentially fraudulent.

called back...went to VM. Did not mention company name.
