[Resolved]  Flipkart — my exchange mobile was rejected

Address:	400701
Website:	www.flipkart.com

My mobile for exchange was rejected by flipkart though it fulfill the two conditions mentioned on their story site https://stories.flipkart.com/smartphone-exchange-deals/

Below is what written on their site:
Flipkart looks at two basic checks on your old phone before approving the product exchange. First, your old smartphone must be in working condition. The second check is on the display and screen of your old smartphone. As long as it is intact and functional, nothing can stop you from exchanging your old phone for a new one.

The delivery boy rejected mobile saying "battery ful (Swell) gaya hai iska" though redmi note 3 have non-removable battery.
Worst experience with flipkart, amazon is far better.
