amazon - i have received damage product i need refund

To Amazon Team,

The objective of writing this letter is to express my frustration with the product, Samsung Galaxy M**s (Mirage Black,*GB RAM,***GB Storage).I find it unsatisfactory that week after my initial request, my deposit has still not been refunded. Let me explain the problem, I ordered the mobile on Oct **,**. Since it was partially charged I used it for * days. But as it switched off, I tried to charge the phone. But ,I found to my surprise, the phone couldn't charge. I tried different plugs and chargers, however it didn't work. So, I requested for a replacement. And When the pickup man came, he refused me to pick it up,as it was switched-Off. He asked for the phone in switch-on condition. But since I couldn't charge the mobile phone, I opted for replacing it. And this cycle happened two-three times. So, I ordered another phone (Samsung M**). Thus now, replacing is no longer an option for me! Now, I want only refund. I talked with customer service, but they don't understand my situation. They keep arranging replacing/pickup service and the person refuses because it's not in switch on mode. Please help me & arrange the refund of Rs.*****/- because I'm tired of this cycle and talked with an illiterate customer representative. Don't encourage me to take other legal action such as complaining in Grahak Suraksha Center. As I have all recorded phone conversation as well the screen-shot of the mails.

I have also attach the grahak suraksha complain mail.
