Myntra.com — Not provided the invoice copy

Address:	282005

I have purchased a watch via Myntra. And at that time there was no invoice copy with the package and in fact, they have also not sent on email as well. And now when I ask for my invoice copy they refused to provide me after making me fool since last 20 days. I need a strict action against the company. They told me that they can not provide me 6 months old invoice but it is nowhere written on their website. Moreover, my watch's warranty was 1 year then how can they deny me to provide me with the invoice. Yeah I know it is my mistake, I should ask for the invoice at that time only. But the problem is that there is some issue in the quality of the product due to which company have extended my warranty.
