Mobile will not getting turned on

I purchased a mobile phone from Flipkart, and the device appeared to function only briefly after delivery. Within approximately two hours, the phone switched off and has not powered on since. Despite multiple attempts to charge the device using the supplied charger, it remains completely unresponsive. This issue was present from the very first day of delivery, indicating that the product is defective. I am extremely disappointed that the return option is unavailable and that I have not received any meaningful assistance from customer support despite reporting the problem. As a customer, I expect a prompt resolution for a product that was delivered in a faulty condition. I request that Flipkart immediately arrange either a replacement of the defective device or a full refund. Failure to resolve this issue promptly will leave me with no option but to escalate the matter through the appropriate consumer grievance channels.
