Caller: Automated call service

had previous calls from similar numbers eg (07) 3517 9105/7 which I'd ignored. Out of interest, called this number back. Answered by automated message which stated "all of our operators are busy. We'll call you back shortly". Have blocked this number

Yeah its a scam

Got a missed call from this number, called back and got automated message :All of our operators are busy. We'll call you back shortly" and I was hung up.

Got calls from this number which I was not attend initially. No voice message left. When called back stated "All our operators are busy. Will call back shortly." Same as what the above comment says.

Then I received another call from the number and the person started asking whether you have savings or equity in home around 150K. When I asked the person what this is about, she said something a government scheme eligibility check.

Felt like a scam and hung-up. Have blocked this number.

Received a miss call but no voice mail message left. Called back and got an automated message saying all their operators are busy. It seems like spam.

5 Dec 2019: I received a call from this number which I didn't answer. No message was left. I rang back but the call went straight through to voicemail with a message saying "All are operators are busy. We'll endeavour to call you back shortly."
I have blocked the number.
