[Q] Colour Chipping

Hi,

Few days back i noticed that there is some color chipping in my s3, inside the front glass at the top of the phone just above speaker. What are my options pls suggest. Service center guys are not replacing it and they are saying it's a cosmetic damage. But as its inside the screen where external force cannot play any role so logically they should change it. Any body else experienced this same issue.
