Flipkart — Product return asking Aadhar card

I ordered Boat 5W speaker from flipkart but recived speaker of 5W but with a different brand ( Tablepro MG2) . So I put a return request on the same day but it was cancelled by flipkart citing the reason that necessary documents were not uploaded .
So I requested return once again and did chat with customer support but they are asking for my aadhar card to proceed return request which is nowhere mentioned in flipkart return policy, also against Supreme Court of India guideline regarding Aadhar uses. So why should I upload my Aadhar card ? I am ready to give all the product related details but Aadhar details asking is legally, morally and ethically wrong .
So I just want to return my product as per flipkart return policy in which nowhere mentioned about Aadhar card .
Please help me otherwise I have to opt some legal means .
My order Id is OD[protected]
