Samsung India — Resurface the display unit of the mobile samsung galaxy j1 ace.

I have purchased one Samsung Galaxy J1 ace mobile set on 11/12/2015 from Amant's Gallery showroom at Kamar para, Jalpaiguri, West Bengal, Ph No[protected] . Unfortunately after two months from the date of purchase I saw that the display unit of my mobile was scale off without any reason but not totally removed. In this situation I can't handle the phone properly though it was on action. I went the local service center. They told me this happen due to poor adhesive which used to set up the display unit. But due to unavailability of this kind of adhesive they couldn't repair it. They took my phone no. and advised me for waiting. In this situation I can't use my mobile phone completely and this is a harrowing experience for me.
I am completely disappointed on the whole matter and I think that it is nothing but a kind of manufacturing defect. So I demand that Company will take necessary action to replace my mobile phone as soon as possible.
