Flipkart — Received different product then ordered

HI,

MY ORDER id OD[protected] received different product, now the seller is rejecting the refund, and flipkart is asking me to provide Aadhar Card with permission to access my personal data to 3rd party service provider, this is really insane & high risk to provide the personal identity to anyone such, that can be misused.. I dont understand why do they need such sensitive documents sounds something fishy. My concern is Just a refund what i paid to the original product i ordered.

This the mail i received from Flikart.:-

"To help you with your return request, please share a copy of either Aadhar (both sides) or PAN card by replying to this email within the next 48hours . Please ensure that the information on your photo ID should match the details on your recent order(s).
We will be validating the ID proof shared by you through a third-party service provider. Please provide your consent to Flipkart for use of the identity proof that will be provided by you for the purpose of authenticating the Flipkart Account. Please share the below clause in the email reply along with the photo ID so we can work on your request.
“I give my express consent to Flipkart for collection, use and/or disclosure of my information provided in this email and the documents attached hereto for the purpose of authenticating my Flipkart Account”
"Here are a few tips to ensure a clear photo of the ID card:
Place the ID on a dark surface
Use sufficient, natural lighting instead of a flash. It's best if the photo is taken during the daytime- Take photo as directly above the ID as possible. Please ensure that your shadow does not cover your ID
All four edges of your ID should be visible within the image
All details on ID should be clear & legible"

Pls help me out to get the refund.

Thank You.
