Hi, i have received a faulty device from mi. Complaint no-1700570. It has been a week time now but no one came to pick up the faulty device for replacement. I am following up with customer care in daily basis but they are not responding and always ask for "wait for sometime". I am living in a metro city - mumbai. Still i am getting this type of service. I cannot expect service of xiomi in small towns. I have buy device with additional warranty which costs me 26000+. I don't want xiomi now and want my money back. Please help me
