Woman stating she was from Telstra and my email is not working.
I don't use Telstra or have an email with them.
Blocked caller

Rang near 5pm on a Friday night, on a public holiday in Victoria. Who ever is calling did not speak. I could hear lots of voices in the background, but couldn't make out the "conversations". Then a minute later got a call from (07) 5211 4006 from Rosewood Queensland. Didn't answer and let it go to voice mail. Voicemail, same "response", no one spoke just lots of voices in the background, but couldn't make out the "conversations". Both numbers now blocked.

Woman called claiming to be from Telstra, I work in Telco and everything she said was incorrect. Scam caller.

yet another dodgy caller with an Indian accent in a call centre

Missed call from this number did not leave a message tried to call back voicemail saying mailbox is full

Man with Indian accent called to tell me he was from NBN and wanted to check our speed on my computer. Definitely a scam.

Said she was from Telstra and then froze and hung up on me, pretty sure it’s spam

My phone blocked it and called it spam

Said from Telstra. Definitely a SCAM!!
