Flipkart — Privacy policy

I have ordered New Balance 880 men shoes from Flipkart but instead they delivered me New Balance 680 men shoes. Now when I requested return they are asking me if I am the rightful owner of that account and asking me to send the scanned copy of AADHAR. They are asking for my consent to use and store that information. They have my number and email with which I am communicating with them. I have ordered 100 of items in the past from Flipkart. Now I don’t understand the need of me providing them my identity. I felt this is a threat to my Right to Privacy. Because without giving them my identity proof they are not returning my product which they have wrongly delivered. I have tried to contact their costumer care executives but they mostly put me hold for hours. I don’t know what to do . Please help me. I am providing you my order details.
