Sony India — Dead Mobile Warranty issue

Address:

Faridabad, Haryana

These days I am having issue with Customer care support of Sony. I purchased Xperia Z1 in Feb 2014 and in 13 November when my mobile was dead I deposit in Support center and they didn't ask for Warranty period or copy of Bill. When i visit 22 November for same they told me that Phone repair estimation in approval process and they forward mail for Warranty period and i just have to call on Monday to ensure same. When i call Monday for this same their reply is same Warranty issue. My Question why didn't as k me for Copy of Bill when it necessary for that and when i ask them on 22 November for that Why they reply they will manage.
