Xiaomi India — Mi4i (sim slot issue)

Address:

In my mobile phone (Mi4i) the sim slot was not working. I went the service center & they told me that it will take 20 days to fix it.. But noy 42 days gone. They dont even call me. I call them the says that it will take more 7 days, then again told me that i have to wait more 7 days. What is this. I am big fan of mi. But this kind of experience i dont expect.. Big trouble. Realy sad for this realy...
