Xiaomi India — Colour of the phone

Address:	122016
Website:	mi.com

I bought the mi note 3 last October. It was a 3 gb ram with 32 gb rom of golden colour.it has been 5 months since then, the phone is working perfectly but the golden colour has faded and it came out to be of something like a silver one. I am amused that a product like this is delivered by xiomi .its pathetic.
Means its totally disgusting.i loved the golden colour.please suggest me what can be done about that.
