[Resolved]  Samsung Corby Pro Gt - B5310 — Mobile Malfunctioned

Address:

South West Delhi, Delhi

I am Saurabh and I bought a Samsung Corby Pro B5310 having IMEI no. [protected] in May 2010. Within few months from its purchase it started showing hanging signs, sometimes while using it switched off on its own. As these problems were not frequently occuring so I ignore it, But in last week of April 2011 my phone completely hanged so I showed to samsung service center in Lajpat Nagar and they changed its motherboard. this change replaced the old problem with a new one, now my phone display(pixels) were not proper and today it started some problem with hearing speaker,its vga camera is gone now.
Now my mobile's warranty is over a few days back and Samsung won't repair it under warranty period actually they didn't even repair it in warranty period properly. Such kind of service samsung provides to its product consumers.
Can I drag Samsung to Consumer court for not repairing my phone in warranty period properly and they make phone for 1 year use only ??
I invested Rs 11,000 in it which is zero now. One thing I am sure in my life i.e I am never going to buy a Samsung Product in my life....
