My mobile redmi 2 prime had some issues with audio jack, so i visited its service center in indore. they told me i had to wait for a month as they did not had the required part on 09/05/2016. after a month they told me that the parts are not available and the mobile will be send to ahmedabad for 15- 20 days. after a month the service center is still saying that the phone is witing for repair. its been more than 2 months. how much time do ther require.? if a product is under warranty for a year and the company takes 2 months to solve the issue what good is that company. my work order number is - ind/xm/16/00577
