Missed call from this number - (02) 9184 9767 - I didn't pick up and they left no message.

I've been receiving anonymous calls from numbers from the same area, same story, one call and no message. I'm blocking them each time, but it keeps coming!

Numbers I've received calls from over the last two weeks include: (02) 9184 9722, (02) 9184 9780, (02) 9184 9760

Just blocked it.

Just another scammer

Called outside legislated hours for cold call.

Unknown number called and left no message. Same old same old….
Getting damn sick of these calls!!!
Unknown number — leaves no message — instant block!
Why can’t telcos fix this?!

Scam

Caller: Scammers

Scammers

Caller: I don't care.

Didn't answer as it is an interstate and not a family number.

Caller: Time waster

Don’t answer, I think they are just fishing for active phone numbers.

Market research but calling after allowable hours

Same with me, I didn't answer and they left no message, then block

Caller: (Unknown) "Phone Room"

Called without leaving a message.
Called the number back (through Skype); recorded message of "Hi, you've called the (unintelligible) Phone Room; please leave a message."

Same message as on (02) 9184 9780 - most likely a telemarketing call centre.

Hung up as soon as I answered.
