Xiaomi — Phone not repaired under warranty period

Address:	440026
Website:	Bangalore

My phone was in warranty and since it was persisting some problems I have submitted it to then authorized service center in Nagpur city. But my phone hasn't been repaired and was returned back. The service center then provided me the reasons behind that, as per them reasons were 1.Parts were not been received from the company 2.Company has been moved its authorization over the service center. The service center, which is not an authorized one now, has also provided me the printed and duly signed agreement mentioning the above reasons and claiming that I should proceed for Consumer Court against Xiaomi. After such, I contacted Xiaomi customer support and the response I got was very bad. I made a call six times and every time I was promised of a call back within aome hours which did not happen. Xiaomi has promised me of my warranty period extension and I have that voice recording too. It has been a month I am facing mental stress due to these people and did not get any response yet.
