Had 8 calls from this number starting at 8.30am Australian EST. NO answer first two times, never leave a message. I just pick phone up and drop it back in cradle as soon as the number comes up

Called but didn't leave a message. Have now blocked number as per comments below on this scam caller. Its about time Telstra stopped on-selling our phone numbers and perhaps being more careful as to whom they give out Aussie numbers to.

Caller: A recording from Amazon

A recording (woman's voice) claiming to be from Amazon stating that my account will be closed unless $99 is paid. I hung up.

Nicely spoken woman (pre recorded message) telling my my amazon account was about to be renewed for $99.99. Pure SCAM

Rang 5 times in an hour, never leaves a message, number now blocked.

Caller: Caller: nbn

Multiple calls from this number this morning.
I answered one.
NBN scammer.

This is the second time they've called today,
but didn't leave a message.

They called but didn't leave a message.

They have rung us 13 times today alone. Multiple times on other days.

Saying they are Telestra NBN

3 calls so far today no one on the line.

had numerous calls from this number when we answer the phone hangs up.

Caller: Brandon from Telstra

I told Brandon that I didn't believe him and he hung up.
Two earlier calls from this number were not answered.

Even if I talk to them, they end up hanging up. Guy named Patrick. 7 calls today so far - three answered to see if I can find out what they want.

Have had 11 calls today!

This number has called me 6 times today, since 8:30am. The Indian woman said she was with the National Broadband Service, she gave me her employee number as V30911233100, she then tried to tell me she worked for Telstra and that she was calling me about my internet speed, when I questioned her she hung up on me.
The scary this is she knew my address

I have had 12 calls in two hours

9 calls in 1 hour, harassment is an under statement

So far today 13 calls within 3 hrs. No message of course.

They have rung 7 times this afternoon, and they ring off as soon as I ask who they are - or if I lift the phone but say nothing. This is genuine harassment.
