Received a call from this NSW number on Saturday at 12:28 - strange time for a business to call. I'm in SA so I was a little suspicious. Turns out to be Telemarketers calling about solar panels - found this out from another site. I didn't speak & just waited to see what would happen, eventually a girl with a chinese accent said "Hello this is Christine, how are you" - Dead give away - they don't care how you are. Waited some more, she spoke again, & then hung up. Number now blocked.
