Flipkart — Exchange denied against policies mention on application

I had ordered Moto g71 with an exchange to my Moto G. Before placing order I checked all Flipkart policies, so that I do not waste my time.

After placing order spent 3 days on backup and resetting phone to prepare for exchange.

Flipkart mentions below policy for exchange:

Issues leading to rejection in exchange
Phone does not switch on.
Brand/model is different from what is mentioned.
Screen lock or iCloud lock (Apple phones) are not disabled.
IMEI, on dialing *#06#, does not match.

On the delivery date Flipkart wishmaster checked my phone as per the above Flipkart policy my phone matches model, correct IMEI, it powered on ok. But still he denied exchange just because of few scratches on back cover that too they were because it is rubbery cover.

All this caused 3 days waste of my time spent on backup/reset, mental trauma and now I have to spent time again on setting up old phone back.

There should be strict action taken on misguiding rules about exchanges and if there are rules setup then wishmaster should not be allowed to follow his own rules.
