Keeps calling & hanging up. I ring back & the number is not connected

Called a few times I the last 2 days, heavy Indian accent, lots of call centre noise in the background, says she's from Telstra Technical Division to advise me of a problem I have, Bullsh*t!! Scammer!

Said it was Telstra and they were disconnecting my internet service for two months. Wanted to give me details of a new service. Definitely a scam. I’m not with Telstra for internet.

Let it ring through to answering machine but no message left by the caller.

I answered and said 'hello' 3 times ... silence, then background noise, then they hung up

Caller: comes up unavailble 0425 868 856

we never answer, let it go to the answering machine, they hang up nothing said

Caller: They hang up.

Great website for sharing nuisance calls. I add them to my list by the phone.

Keep calling landline and not leaving a message. Happened several times today.

Pause after I answered, and then connected to woman with a strong accent claiming to be from Telstra technical centre. I hung up.

They've called my landline a few times without leaving a message on the machine.
