Samsung Customer Service — Worst service from Samsung

Address:

Pune, Maharashtra

I have purchased a touch screen mobile phone samsung start (GTS5233W), however the touch screen has stopped working within 6 months of purchase.
I contacted the Samsung Service Center and they cant guide the customers correctly.When I visited the Samsung service center , they are unable to fix it as they dont have available parts for the same.
Its been 3 weeks , i am unable to use the phone and the samsung service centers are just pathetic.

Samsung's service is the worst.
