Prefix (02) 9247

Caller Type: Scam

This whole series of related numbers commencing with (02) 9247-6*** seems to be bulk scamming but list as (02) 7247-6*** when displayed on my phone. Series starts as low as (02) 7247-6201 and over (02) 7247-6794. I scanned through the 'Reverse Australia' website and found 60 listings just for Nov25 and NOV26 only. This series identifies as Central Sydney ????? Could be anywhere. Can't Telstra do something about this???
