Nikon 5200 with Kit Lense issue .Service Center of Nikon in Ahmedabad

Hi, i am a new user for forum and i like etalkindia.com. This forum looks really nice with nice colors and design. Now, my problem is i just buy a Nikon 5200 with Kit Lense. It was a nice gadget at per it's price tag. After 2-3 days with It I was happy but after some time I spotted A Spot in the View Finder It Was A Manufacturing Defect which completely breaks my mind and i feel very disheartened.

Now, i am new in ahmedabad, and i didn't know a single place over here. So, if anyone out here knows the service any Nikon service center with excellant staff. i don't wan't lazy sick people who makes the problem more worse. So, anyone out here knows what is the manufacturing defect and knows how to fix it or if he knows a service center for Nikon then do share it overhere.

Thanks in advance.
