Returned my faulty tab but could not get the refund even after more than a year

Hi
I am Rupesh Sharma from Bihar, i bought zync z99 (company website : zync.in) tablet from Snapdeal.com an online purchasing site.

I was delighted to get my Tab but while using the Tab I had been experiencing some trouble in my Tab. Like when I switch on my tabmany of my applications don’t respond. Even after switching off the vibration mode my Tab vibrateed. I saw screen was also very fragile. Speakers giving horrible sound. As the Tab was in warranty with pick & drop facility, I called the Snapdeal.com and demanded the refund. They told me to contact the company, When I called the company they assured me that they’ll pick up the product soon. Approx 3 months passed during those days I requested them many times to pick up the product. Every time they promised to pick up the product they were giving me false assurance. Finally I sent the Tab on my own expenses to the company and asked them to return the money or the properly working product. Later, they started demanding me Rs. 2000. They didn’t want to give either the money or the product. Every time I call them or mail them they assure me for help but do nothing.
Now as more than one year has passed still I have not got justice. Now I want full refund of the product. Please help me to get the refund.
i got frustrated with the zync service and i request you to take severe action on them.
we should not encourage such companies in our country, they will spoil the world.
