I didn't answer because my phone identified this as Potential Fraud—I'm glad I didn't! The number is now blocked on my phone.

Probable spammer, seems to be multiple business names, for this number, on reverse australia lookup site.

Called me and left a voicemail

Didn’t recognise, didn’t leave a message. Blocked my no and phoned back but ‘disconnected’

Keeps phoning, no message left, but when I tried to phone back I get "your call could not be connected" automated message. I suspect it is a spam caller.
