MSI
Not replacing/repairing its faulty warranty product

I purchased a game card of MSI around 8 months ago with 3 years of warranty. Now it is showing blurred picture quality, so I went to there repairing centre at Nehru place to repair the product but they refused to do so and was making useless issues. I am very much frustated with this as I had spend around Rs.3000 for this product.

Please help me in getting this resolved.
