Unknown number twice called. No message left presume spam & number blocked.

Variations of this number located in Sydenham Vic calling me upwards of 5x per day. Wish I could block them all at once.

For the last few days I have been receiving calls from this number and very other similar numbers (with the end 3-4 digits different) from Sydenham, Victoria. I answered once, there was silence for 2-3 seconds, and a female voice (probably recorded) just said 'Good Bye' and the call disconnected. Since that call, the calls are more regularly coming around the same time in the morning, which of course I am not picking up any more. Is there a possibility my Iphone is hacked???

Same thing here, 2 years later. Called twice, hung up when I picked up

Unknown number called 7 am didn't leave a message. Spam or scam

These guys call from Sydnam Victoria they have many different numbers with the same prefix , they leave the line open and say goodbye,
I think they are trying to get voice recognition information from anything you say , but I’m not sure.
