I had the same robo call stating same amount - $299 - from (08) 7077 7410.

They said they were from eBay. And that’s there’s a purchase from my account of $299. Confirm if it’s me but they argued with me how to react to this transaction. They also didn’t want to tell me who they are and where they are from and how they got my information. I hung up and then a mobile number called with an automated voice saying the same thing
