Said he wasn’t selling anything- about my nbn

Said they were calling from Amazon and my account would be debited $99.95 cents. Press 1 to speak to someone from their accounts department. Didn't press and hung up. I imagine if I spoke to someone they would try to get my credit card details

Picked up - second of silence - immediate hang up

Scam
