telemarketing

These people get nasty if that's what it takes to make a sale. Increasingly aggressive repeat calls, starting friendly, but getting more full-on each time, with insistent sales script tactics. I would have been interested in their product if they had been respectful: IE: allowed me to call back at a convenient time instead of harassing me with numerous calls, using increasingly pushy language, and ultimately refusing to remove my number from their list. They also had my address, which was creepy, given they talked about technicians in the area - they had better not show up at my door!

Calls. Hangs up. Repeat.

Junk.

I called back number (03) 9553 0702 rang once then goes to busy tone.

I had a missed call from this person - no message left. I'm in the ACT so a bit dubious about an unknown interstate number.

Missed call from this number, not entirely who it was, called back and number was busy.

Unsolicited call asking if I want to talk with a 'service technician' who is "in your area" about solar panels.
No hassles, the guy was polite and readily took "no thank you" for an answer.
