Caller: Claimed to be from Telstra

They had a lot of details about my phone account. I think it's a Telstra agency trying to rack up sales.
I would advise against dealing with them.

Caller: David

David is connected to Vinamra Sonkhiya who called on (02) 8213 0882
pretending to be Telstra rep and wanting me to sign an online document

Caller: John

Said the we’re offering bookkeeping services

Call constantly but never leave a message. The one time I answered there was a long pause before it went through to a call centre. I hung up before they got too far into their spiel. Blocked.

Caller: Derek

Fake Telstra, had ALL my details.
Said I owed them $108 and that I was eligible for an offer. Aggressive guy
Hung up on me. No response when I called back.
SCAM

Cold call from above number, stated they were from ‘telstra’. Had some information about a phone upgrade. Scam

They hung up before I could answer it. Have marked the number as 'SPAM'.

I called back number (02) 8004 5830 rang once then gets disconnected automatically.

Pretended to be a Telstra rep wanting to upgrade my phone and plan, then wanted me to sign online agreement and he would call back so I called Telstra to double check and yes it’s a scam!! Beware
