Lana (?) from Telstra Mobile wanting to apply a 40% discount to my monthly billing. 2nd call from same place/person today hahaha. Had to break it to them that I'm prepaid and don't pay monthly.

Caller: pacific outsourcing

Called to confirm the appointment of their services – we have never heard of them
They asked for my boss by name and were advised that they were “unavailable”
The caller then asked for a person named Jason, we have never had a Jason working for us.
Scammer!

Caller: Claiming to be Telecom & it's the last call regarding unpaid bill

Toll scam, just hang up & make sure you block the number

Started by telling me they were from Vodafone then half way through the next sentence said they were from Optus. Said they would give me a 50% discount on my next bill but they needed my 4-digit code to verify my account. They never asked my name and I never told it. I made up a 4-digit code, they said it wasn’t valid, did I have another? I said the fake one backwards and that didn’t work either. So they asked for my date of birth, I gave a fake one. They then told me to call Vodafone customer service to reset my 4-digit code and they would call me back another time to try again.

Caller: Scammer

Caller pretended to be from Vodafone billing. Scam alert.

Caller: Says CommBank but think it’s a scammer

Says it’s from commbank and teller named olivia

I received a call from this number. Suspiciously didn't leave a message. Based on numbers above, it appears to be spam/scammer.

Caller: PayPal?

Voice recording saying they are PayPal and press 1 to dispute charges. I just hung up.
