Caller: unknown...identified as telstra....

pre recorded message says my internet is going to be disconnected..then hangs up...have had a few calls...

This is a ‘wangiri’ scam where they charge you money when you call back. They have called me 24 times disguising themselves as overseas numbers from Austria, Tunisia, Nigeria......etc. Absolutely disgusting, I hope someone can investigate this! It would make a great story investigating who these con artists are. Like that podcast from Reply All who takes on those call centre scammers.

Number identified as "Bonbons bakery". Didn't answer as I've never heard of this business. No message left.

Caller: Not sure

Went to a dial tone straight away went attempting to callback

I saw a missed call from this number as I woke up early in the morning. The time of call was interesting: 4:30 A.M. !!!

Caller: tax scam

say my tax file number is related to suspicious activity and will be arrested if no further information provided. obviously, it's a tax scam

Robo call claiming to be from Dept of Australian Tax Office stating that tax file number suspended due to fraudulent activity.
Call reported to scamwatch.gov.au

this number called and hung up. Google shows it belonged to a business that has shut down.

Claiming to be the ATO and says your TFN has been suspended due to fraudulent activity. When you ask them for their staff number they hang up. Don't fall for it!

It was a scam message from a robot saying they were from Telstra and that my internet was being disconnected

Caller: they said it was telestra

second time I have received this. Am not with Telstra. fake caller.
