They call me 5-6 times and they know my name. They ask me about my PC and when I try to end the call they become very aggressive and keep calling me again.
Neighbour.

Have just had the 10th call from this number today... and the days not over yet! I'm certainly over it though!

14/4/14. Just had three in a row from this one! Same claim, but this time added that 'we've had lots of complaints from people in your area have material downloaded via FaceBook', the rest was identical to the above. Even when I told her to 'shove it', she still tried to phone back two more times.

Hi guys

They are still trying this on April 2014

There should be something done about this.

State or Federal Consumer laws

International Law ??

Scammers harassing my mother inlaw. Love to get my hands on them and ring there neck.

My parents had 10 calls from these people in less than 90 minutes. Mum kept telling them that the owners weren't home, but they kept asking about her computer. She kept hanging up, they kept ringing back. Massive scammers.

Scam from Indian call centre claiming to be from Qantum - hung up when I asked questions.

Recevied phone call from the number above. After she explained that she was from Quantam and had concerns about my computer I advised I was not interested and hung up (I had heard of this scam before). They rang three further times, eventually I called the number back so I could ask them to stop calling. They hung up before I could say anything. Now I am getting calls approx every 5 mins from a "private" number and there is just silence on the other end of the line. I have just put my phone on do not disturb, and submitted a complaint to Telstra

This number phones every 5 mins and they are a constant pain if it isn' from this number it will be from 08 or 07 or a 03 number can normally tell it is them as there is a long silence I now just answer and hang up eventually one day they might stop . This has-been going for about 8 weeks now

Called constantly all day and no one there and then changed to a different number which I am told by Telstra that it is the same no.

This number called me 9 times in the space of 90mins. I eventually answered the phone to tell them to get lost (as I had gratefully read all these comments). It was Quantum calling and when I asked them why they had called me 9 times in one afternoon the guy denied it. When I asked them not to call me again the guy kept trying to persuade me to listen to what he had to say until I raised my voice and he hung up on me. My husband works shifts I don't want them calling every 10 minutes. Wish someone would do something about them.

This number keeps call and asking if we are in front of our computer. As soon as I advise them we are a computer business they hang up. If I state we are a computer business first they hang up with no response. This number is calling 2 to 3 times daily

These people are SO annoying.. Must be using an auto-dialer.. New phone call every 10-15 minutes from this number, no one there.. Rang quantum PC on the (03) 9999 7448 to ask them (for the 3 time this year, even changing providers) to remove my phone number from their call register.. There has to be some way of reporting to someone??

They never speak to me, I just "hello, hello.."
When i hang up i check the number and it is the one above.
So the cannot be traced..?
Love to catch up with them

well its my time which equals money when I have to stop work to anwser these calls, whats more they call early on a sunday morning now too. Whty can't this number be blacklisted

After a while of this number NOT calling me, they have decided to start calling again....

Getting about 4 call a day from that number, nobody on the other end these days. Why can't the number be shut down by the authorities or Telstra etc? Very annoying.

They don't give up because eventually they find someone who falls for their scam.
