Consumer Redressal

I had purchased a BlackBerry 9300 during June 2011. There were many issues and problems in that. I approached the service center. After rigorous chasing, I got it replaced. The problems subsisted in the replaced handset also. Again I approached them. I got it replaced again. But the problem still subsists. Thereafter, I have followed up them many-many times. But, they are not responding at all. Now, it has been two years of sufferings. Being in Mumbai, I have visited the service center many times, at least 6-7 times. It is really very painful and exasperating. I have got the solution yet though I have sent them the pictures of my device taken while the problems surfaced.
