Australia Reverse Phone Lookup

These idiots call and distract me from my work. 3 times in the last week. I ring the number back and get elevator music.

Telemarketers trying to sell financial advice. They have called me at least once a week for the last six months. Each time I tell them to remove me from their list. But still get them ringing me again & again.
Please stop I trying to work.

This number calls regularly and hangs up as soon as I pick up. Looks like a Gold Coast number, I'm nowhere near that area.
In addition, when I phoned the number I got a very vague answering machine that tells me "you've called customer service" and they say it's outside business hours (in the middle of the day).
I've left a message warning them that I'll be taking federal action under the telecommunications act if they call again. We'll see.

Telemarketers trying to sell financial advice. They have called me 5 times over the past 3 months. Each time I tell them to remove me from their list. They say that they will but never do!
