Called me claiming to be from Amazon about cancelling my Prime membership, which has already been confirmed in my Amazon account

Didn't answer. I'm in Sydney and don't know anyone or deal with any businesses in the (08) area code.

My phone flagged it as potential fraud. I didn't answer and they left no message, so it's probably not someone I would voluntarily talk to!

Caller: Cryto investment company?

(08) 7092 2597 - picked up this call, caller said he is calling from a Cryto Investment company, I told him I am not interested and hung up.
Within a few seconds, received call from 0480 900 006 - the same guy - I hung up!
Another few seconds, received call from (07) 3073 1451 - the same guy asking me not to hang up on him - I hung up and blocked all 3 numbers on my mobile.

I've been receiving a lot of nuisance phone calls lately that hang up 5 seconds after connecting - without saying a word. I wouldn't be surprised if the caller is a bot that is recording your greeting, and building up a database of mobile phone numbers and associated voice prints. The danger here is that greeting a bot caller could potentially provide enough info for a deep fake of your voice - enabling hackers to do steal your identity more easily. As a result, I don't even say 'hello' to any incoming calls that are not known to my contacts list. I wait until the caller speaks first. Nine times out of 10, it isn't a person calling anyway.

Didn’t leave a message. Scam

Caller: (08) 7092 2597

answered call. female computer voice spoke. Stating that they were from Vodafone and that the network was going down for maintenance. Press 1 for English or 2 for Chinese. i did not press any and left the call on speaker phone. The same message then replayed itself and i left the call. TOTAL SCAM

Scam says from visa press 1 if you think your account has been breached

Caller: Asian lady

Said she was from 9 King WIlliam Street, Adelaide, had no idea about Adelaide I said it sounded like she was more likely from 9 King William St, Bangkok. Anwya, she was trying to siphon information using accident insurance as a scam.

Let phone ring out & went to message bank, no message left so I assumed it was a Scam!

Caller: (08) 7092 2597

Claims to be from Telstra technical department stating problems with my account. I do not have a Telstra account.
Scam callers

Claiming to be from Amazon prime about my account - I don’t have one. Spammer/scammer

Thanks WCM!

Called, saying they were from Telstra, my internet speed from their observation was getting slow and were offering to upgrade the internet to increase the speed.

Said they were from Telstra calling re my NBN/Internet.

Didn’t answer as I’m in NSW & know no one in Adelaide

I live in QLD. Call is from Adelaide. They didn't leave a message.

No one from Adelaide calls me, so be warned it is most likely a scammer!
