I have purchased a mi 4 handset (Xiaomi product) online on 7 - february -2016 from flipkart.com, this phone working fine till 25-june 2016 then suddenly its turned off so i submitted my phone to their authorized service center based on lazpat nagar new delhi, however its more then 60 days and they are not be able to repair the hand set i have also called to the mi customer care center even they guys are not be able to telling me the current and correct status of my hand set, i don't have any trust on this product any more, and they have almost spoiled 2 months warranty of my phone as my phone is in their service center from almost last two months, i want my money back with all the losses which i have to bear due to their poor service.
