Blank call, I took the call from (02) 8073 5012, but Noone spoke & hung up.
They try from different numbers. Scam, block these numbers, beware.

Caller: Random solar panel company

Scam call. The don't know your full name but surname and address. They want to speak to the homeowner. Indian accented.

Male with foreign accent (Asian like) claims to represent a Solar power company.
I asked how they got my number as we are on the Do Not Call Register. He hung up.

This is a scam number

I missed a call and tried calling back but call won't go through

Caller: Solar Panels

Unclear name claimed to call from a company called Solar Panels. Told me that I'm targeted for the call as a home owner (I'm a renter) because government is granting 40% rebate with a GUARANTEE of a 90% saving on energy bills. LOL

Caller: Lucas Beashel

We too were scammed by this company. They seemed legitimate, but after we created a bank transaction, they have stopped communicating! They are felons!

Caller: Commonwealth Bank Scam

Said he was from the Commonwealth Bank and someone was trying to get in to my account.
I hung up and rang the number back. When he answered I asked which company I was calling and this time he said Telstra.
Also used (02) 8073 5033.
