Flipkart — Nothing ear 1 buds

I ordered nothing buds 1 a week ago, on 21st April and received it the next day, but inside the box was a product of different brand. So I made a replacement request and they asked me for my ID proof, so I sent my full aadhar e-scan copy. They rejected it and made me resend it, and I did, after that they asked me for the pictures of wrong product. I sent them the pictures, and they still declined the return request. I requested callbacks and they either call for a second, end it and then message me that they're not able to reach me, or they put me on hold for 5 mins and just disconnect, they never provided a resolution. So I made another replacement request, and they asked me for all the id proof and pictures again and they still rejected it. Yesterday was the last day to return to I made a return request, and they rejected it without any reason and won't replace it, so now I'm stuck with a wrong product and they're not providing a solution. The customer service doesn't care about the customers at all. I need a replacement/refund for the wrong product that they've sent me.
