The same thing happening here, keeps calling and doesn't leave a message. These scammers are using different numbers all the time. Blocked the call by automatic reject to avoid leaving a message. Beware, overseas scammers are using Australian local numbers.

Answered call no one there. Keeps calling back

Same thing, returned call and directly went to hold music "An agent will be with you soon?". So i hung up

Another one of those relentless scam callers.
Seems all they want is for their call to be answered so that they can sell the number on as an active number.

keeps calling and never leaves message and doesnt answer call back

Caller: I don't know

I called back as well on 4/9/18 but it was on music and no one answered the phone.

I called back number (02) 8363 1252 was put on hold music but no one answered the call.
