Caller: Claimed to be Alex Williamson

Pretending to be with Telstra Technical Department and that they needed to disconnect our NBN as we had unusual activity appearing.
I rang Telstra to verify and they confirmed this number is not a TELSTRA PROVIDER NUMBER - Do not answer these calls

Caller: Someone stating they were from Telstra about my internet and phone line

I asked her to provide the name for the number she was calling. I said "if you have the right number then you should know my name", she said "Oh Miss Lawyer". Told her wrong number and nice try for the 5th time trying to scam me, she very quickly hung up.

Caller: Telstra - at least that was what I was advised

A heavily accented woman advised she was from Telstra and ringing regarding the NBN. I disputed she was from Telstra and advised we were not scheduled to get the NBN for another 14 months. She advised she will send a technician on Monday (next working day) and she hung up when I said 'No, you will not send a technician out.' Rang the number back but it just rang out each time. Obviously not from Telstra ... I have now blocked this caller from contacting me.
