When I was travelling a couple of months ago I enquired with Matrix about their product. After that I told them I was not interested. However they have kept hounding me and my wife and have atleast called fifty times. I have kept telling them not to call me or my wife but they have still persisted. The most amazing part is that it is the same guy again and again by the name of Samir(Mobile Number: 9820134159) who keeps calling again and again and again.
SO I would suggest to everybody never to ever give your mobile number to the matrix guys ever
