Amazon India — yureka replacement

I have registered a complain about my phone YU YUREKA model no. AO5510, my TICKET NO.#1017387, IMEI1 NO:[protected], IMEI2 NO:[protected] on the customer care of yureka. The screen of my phone has been broken as it had fallen down. The solution given to me was that you would replace my phone. It has been 7 days since i have registered my complain. They were to send a person who would replace my phone and i am ready to pay RS.2999 according to their terms & conditions. I had talked to Ms. Shrushti about this matter. She had noted all the details. Now when i am calling to check the status of my complain they are not responding to me at all. They are saying that their seniors are busy and also they cut my call. I am suffering from this problem from since 10 days and i am not getting any response from their side. I request you to kindly see through my matter as i cannot access my phone due to broken screen.
