Silent call from unknown number.

Didn't ring for long & No message was left so I'm not calling back to find out who it was or what it was about. If it were important surely they would've left a message

Left a voicemail but I think it was an accident, sounded like a VoIP or a headset because the mac turned on after a couple of seconds, then an Indian guy with poor mc quality said bye and hung up.

Spruiking ‘unsecured loans’ Sounds like from a call centre in India.

Didn’t answer no message left.

Scammer

Caller: A silent caller from a customer service centre

It's a scam. Don't pick up. They're checking if the line is active to sell your number to another scammer. That's what I think
