Hung up, did not leave message

Said they were from the NBN and someone was using our internet connection outside the house. Scam

Hung up, did not leave a message.

Caller: ‘Amazon’

Said they were from Amazon and said it was regarding my last order but then asked me if I had ordered anything recently??? When I said no they hung up? Scam. Phone said call was coming from Melbourne, VIC.

Said he was from Telstra, and that there was an Internet problem. I told him I worked for Telstra, and asked for a phone number to call him back. He hung up. Quite insistent he was from Telstra, but clearly wasn't.

Phoned and did not leave a message. Can’t be genuine. Now blocked. Why return their call ?

Hung up as soon as I answered. Phone said it was coming from Melbourne, VIC
