[Resolved]  Samsung India — damage not claimed under warranty

Address:

Belgaum, Karnataka, 590006

I had purchased my phone 2 months back i. E on 29/08/2017 and theres a pink patch on the right side corner of the screen all of a sudden (The phone didnt even fall). I had been to the service station and they said it cant be claimed under warranty. They showed me three to four phones which had the same issue.
How can there be four phones with the same issue at the same place.
And what issues are covered under claims then?
Having a problem like this within such a short period of time is a sign of bad quality maintained by samsung india.
Kindly suggest as the amount required to replace the display is 5k which i believe is too much and should be covered by the company in warranty.
