scammers re supposed debt from Amazon or similar.

same Amazon scammers

I didn't pick up the call, and they left a pre-recording voice message saying my internet connection was compromised... I simply blocked the above number to avoid receiving further calls from them.

Scammer asking for my IP address from Telstra.

I have no idea who they were from as I couldn't understand what the person said. But I've had enough scam calls to know when to hang up.

left a short voicemail sounding like a call centre in the background

Left me automated voice message in Chinese language.

Caller: Scammers

Automated message stating I was being charged by Ebay for $299.99 press 1 to cancel transaction press 2 to claim refund. Did neither, hung up and blocked.

Yet another scam calling claiming to be from Paypal and they are going to debit $999 from your account. You must press 1 to decline or 2 to authorise.
They have a billion different numbers.

Claiming to be from Mastercard Visa saying their is a payment of $1300. Scam

Caller: “Telstra”

Said they were Telstra and said my IP Address was public and not private. Asked me how many green lights were actived on the back on my modem. Said that I could email them or call them back if I was busy - it was along the lines of Telstra @ au.au so idk how that works… but anyways I was wasting his time saying I’ll call them via the number on their website and he’s like oh no no call back on this number instead… total scam

Claimed unauthorised withdrawals from my Visa card . Said I'd check but found none. He had hung up in the interim. Blocked the number.

Stating that my Woolworths Credit Card ending in XXXX had been used for transactions including ebay for certain amounts. Told him I would call him back via Woolworths Contact Numbers only to find out that no one had called me however unauthorised transactions have since been attempted. They were obviously trying to alert me to these amounts so that I was under the belief that they were already being investigated.

Caller: Scammers

Claiming to be from eBay, recorded msg. Said was going to charge my eBay $299. I disconnected call and blocked it

scammers - recorded message pretending ebay purchase for $299 and will debit the transaction. hang up

heavy Indian/Pakistani accent, said he was from Amazon Prime and they were going to charge me $99. I hung up. Phone number disconnected by scammer shortly after

Scammer pretended represent EBay.

Scammers - tried to say they were reporting unauthorized transactions from EBay and Amazon

Didn't pick up and they didn't leave a message, so I am guessing what Geoff said ... scammers
