Telemarketing company, calling "on behalf" of 'Energy Australia'...offering 14% discount...requesting personal details (DOB...etc...)
hidden issue: booking you for a new contract 3 years....!

Repeated unwanted calls received from this number. When operators have been asked not to call again, their response has been threatening, harrassing and abusive, with one operator in particular repeatedly calling back, yelling " what's your ** .. ** problem..." There have been repeated nuisance calls from this number over a period of several months (December 2012 - late February 2013). One abusive operator has called repeatedly, apparently making a sport out of upsetting my wife who is unwell and seriously stressed by this unwelcome intrusion and abuse.

Unsolicited phone calls, persistent and unwelcome. Hung up on me when I told them their calls were unwelcome.

Calls and Hangs up

This is Australian Green credits and telemareting services. They ring and before you can answer they hang up. The telemarketer is just going through the motions of making calls, but sick and tired of rejections. They work on auto dialing system so they just give themselves some breathing time by rejecting numbers themselves.
