Xiaomi — battery drainage in mi band too fast and not proper customer service

Address:

My mi band's bettery drains in 6days. And they provide guarantee of 15 days bettery running. After 4-5 times replacement from the service center. Still I am getting defective product every time. After completing about my problem, they are not responsible. They just provide me long running process to follow, instead replace with fresh piece. When I went to service center their behaviour is not good. They misbehaved with me and also make me feel that I don't know how to use their product. Their product is working properly.

I am suffering with this problem from almost 1 year and now I have like few days left. After 6th April my 1 year warranty is ending. So then they will do nothing about it. Currently my product at a service center, and they are not provideing me with fresh piece. They say just take your product, we replace it but don't provide any guarantee that it will work.

And when I called to customer care number and mail them they just taking longer time and asking me to follow cumbersome processes and just wasting my time. And not provideing me proper solution.
