It’s always annoying when you get calls and you can’t find out who is calling you. I’ve tried calling back, but there is a message that says your call can not be connected.

They leave me voice messages in a foreign language, sounds like Chinese. Get at least 2 a day, I've blocked the number but they just call from a different Sydney number. If you answer it's the same automated message.

Just got this call as well. Looks like a spoofed voip number.
This shows that the number belongs to Symbio Networks based in NSW which is where I used to work

Scam, do not answer

Called me and left a message in Chinese I think

I did not recognise the (02) number, so I did not answer. The caller left a voicemail and it is a Chinese voice, so it is a scam call

Who is this
