Started with a voice message saying someone was trying to buy a gift card on my eBay account. And then connects you to a call center - who ask you to d!
/l an app so they can connect you to the eBay secure server. They were unable to verify they were eBay - or give another number for me to call to verify.

Scammer. Overseas call centre pretending to be from eBay. Blocked!

Caller: Apparently Ebay

Advised me someone is trying to purchase an ebay gift card on my phone number. Did i want to cancel the order.
Sounds like a scam....

Caller: Automated call claiming to be eBay

The computer voice reported that eBay had a request to debit $200 plus from my account. I was asked to call on a number impossible to grasp or press 1 - 2 - 3 for various options. The call ended with another voice sounding more friendly

Caller: unknown

Recorded message advising that a debt of $9.99 would come from my account. If I did not place the order, press '1' now.
No name or company given to identify who was calling.

I called back the number (03) 9109 6267 and reached vm that said I called an "outbound only phone number"

Seems to be an EBay gift card scam coming from an overseas call centre.
