Sir
I Mr ABUZAR K HOSSAIN bought a red mi note 3 32 GB mobile from amazon dated 14/05/2016. Now this mobile is completely dead and it is in authorised Xiaomi service center, SILIGURI; WESTBENGAL from 3/08/16 bearing job sheet no JS[protected].In the time of receiving they told that I will get it by seven days.But unfortunately I am not get it.

They told the parts are unavailable.It will take more days.They are unable to give exactly how many days it will take to repair.I also told that if parts is not available please give me a letter that we are unable to repair it so that I can get a new mobile by replacing the old mobile.But they are not listening to me.I also told them, ok in that case please give me another mobile from service center so that I can use it for the time being.But they are refuse to give a another mobile to me.

Now you tell me what should I do ?.I am trying to contact with their service by mail but all are in vain .I am really upset
