Apple India — iphone 6 32gb colour is losing

Address: 147001

I have one month old iPhone 6 32gb gold colour and now it’s colour is peeling/losing and I contacted with apple customer care and service centre but they are saying this thing doesn’t come under warranty and that can’t do anything. I spent 28000 on this phone and within a month it’s colour start peeling and it’s a mobile company hardware fault so my iphone must be replaced.
