Xiaomi India — rejection for replacement for redmi 12 5g purchased from flipkart

I had ordered Redmi 12 5G for INR 11058 on 8th April 2024 with Order ID OD[protected] from Flipkart. I received the product on 10th April. The delivered product is a defective one. Now Flipkart is denying for replacement and so the service centre. Flipkart is sending me to service centre for replacement and I have visited service centre but they denied the replacement and asked me to connect with Flipkart for the same. I again contacted with Flipkart customer support but they are denying replacement and again asking me to visit the service centre. The service centre is very far away from my place. I have already visited and faced rejection at the service centre. I want to get it replaced as soon as possible or I want to return the product so that I could get refund for the same.
