Caller: Scam Call Centre

Claiming to be Telstra Tech Support calling me on my 'Do Not Call Register' listed mobile number about my internet.

* Firstly, 'Do Not Call Register' listed number.
* Secondly, I used to work for Telstra Tech Support and they do not cold call anyone.
* And finally, and probably most importantly, I don't have an internet account with Telstra or anyone for that matter. I use someone else's internet account and my mobile number is not associated with any internet account.

I didn’t answer and no message was left.I called the number back and received a recorded message saying the number you have dialled is not in service.
I concur with the other comments don’t give any personal information out as it looks like a scam call. Be careful!
