One of them numbers to check and see if your home

No message left, but I suspect is the same caller as (03) 8609 0063 and 0074 who called the following days and are spam.

scam

agree 100%. chasing people to still information and money if possible, they have the technology to make you think thourgh your mobile ID that they may be calling from AU or any other country, but may not be true. I have received calls from Spain telling me that my international Amazon account had a suspected transaction and that i have to check for my self , then they want want to send me the link to do so, any many other things like that. .

scammers, lowlifes, oxygen thieves

Repeated calls.

Caller: Scammer

Checking to see if you're home...
assuming someone else will call from a different number.

scammer, don't pick up

Fitzer scam

A large number of robo calls coming from this number and others in same range.

Please note that this scam is checking if your number is in use. That's why its a robocall. They on-sell the number in a list to scammers who then send you text messages, it's all a big part of a network of scammers. You will then receive SMS notices claiming to be Australia Post, or any other parcel delivery company and to click a link, they are after your credentials etc.

You will also receive robocalls from ATO or similar saying you have a warrant for arrest etc.

Ignore, hang up immediately, no company that is legitimate will do robocall recorded message voice to you.

Calls frequently. No one answers.

Caller: No one spoke

Silence for 6 seconds

Install HIYA scam blocker on your mobile - I did and it detected this number and also, (03) 8609 0063. No need to pickup call. Another nuisance scammer

This is a nuisance number, call you, but no-one is there. What's the purpose of these? What value is it to them to call you? Presumably it's some automated process, hooked up to an autodialler?

Another landline number that hangs up when you answer. Is a checking service to see if your number is live. When you ring back it is never answered or diverts to a voice message that says the mobile is not connected. Block it.

Only ring to see if someone answers
