Flipkart — Order ID OD[protected]

I have bought blue jeans which was delivered on 1st Sep 2022, but different size, so requested for return for the same.
Now, Flipkart is not accepting return saying that it should be black one as photo is showing black..

I have not posted photo which was posted by flipkart seller only.
Customer care is not helping for the same.

Return ID[protected] was rejected with reason that jean should be black color, but blue jean was delivered.
Return ID[protected] was cancelled without discussion.
New Return ID[protected] is open as of now.
