I called back number (02) 8378 7957 it says the number I have dialed is not in service anymore.

Caller: Recorded Amazon voice

Well, this number is back in service!!! It waits till you say 'Hello' then a recorded voice identifying themself from Amazon stating something about outstanding monies for some rubbishy order. I hung up & blocked this contact number.

Caller: (02) 8378 7957

every day same time. Scam saying I purchased a $340 item on Amazon which never happened and then if you click to ask you get connected to a scammer trying to take your money.

They left a message saying your $379.99 dollar amazon delivery needs to be confirmed (I didn't order)
There was around a 4-second pause at the start and its a robot speaking.

they are annoying
