Damge Phone ka refund na Krna

I purchased a Realme phone online through Flipkart. When I started using the phone, I found that the microphone was defective. I raised a complaint with Flipkart about this defect and requested a return/refund, but Flipkart refused to take it back. I then contacted Realme for help, but Realme also did not resolve the issue and told me to visit a physical store to sort it out, even though I had purchased the phone online. Since I bought the phone online, I expect support to be provided online as well, not be redirected to an offline store. I had taken a loan to pay for this phone, so this issue has put me under financial and mental stress. I request that Flipkart and Realme take responsibility for the defective product and provide a replacement or full refund at the earliest.
