3-second message left, obv from a call centre

Just received a phone call from this number. It seemed suspicious, but I picked up - no actual person was on the line. A recorded effect played (I've heard these before when phone numbers are being given to people to scam the answering party). I blocked the number.

Caller: Claimed from Amazon

Robocall claiming auto renewal of Amazon prime and to press 1 to speak to cancellation department. Clearly scam - block number and complain to your telecommunication company for letting scammers thrive!!!

I receive multiple calls from this number no messages left

They said they were from Visa security calling about transactions made on my behalf. They hung when I started asking questions.

Caller didn't leave message on answering machine, when I called the number back, there was a recorded message that the number is not connected.

First said he was from Telstra and I could hear someone in the background saying 'Hello' 'Hello' and then he said 'I want to f*&k you f*&' and then hung up. Truly bizarre.

Interstate call. Didn't leave a message

Called the number back and message saying number is not connected. Obviously a scam call.
