Caller: Apparently Amazon

There was a huge pause before they answered ‘Hello’ once i answered - Caller used first name said that i had made a large purchase on Amazon and they are checking if was me & if not would i like to stop it - played along then said i need to out you through to Australian fraud squad to investigate. I need to take them off speaker phone & be on normal call so i could be transferred. In the background you could hear lots of callers chatting away. Told them that its BS and take me off list
& hung up - i never store my cc’s in the Amazon wallets so i know its not true. Scammers
