But the has not been delivered till now I mailed to Mi India they just told me they will see in to my matter and I will get it in 48 hrs but again I didn't get anything. Now I am totally frustrated by all this stuff. Blue dart have to send me the consignment but still they just ignored my request. I am eagerly waiting for my product but this type of poor Customer service ruined my mood. I just want my product please help me out.
