Amazon India — Non Delievery of my order

Address:	New Delhi, Delhi, 110045
Website:	www.amazon.in

I had placed order #[protected] for Xiaomi Redmi Note 3 (Gold 32GB) on 4 May 16 on Amazon.in. As per their tracking details my order was supposed to be delievered by 09 May 16. But once i launched comlain after non delievery of my parcel, they told at the max on 12 May 16 my order will be delievered. On daily basis i mailed, called and chat with their customer service agents. But there was no fruitful reply. Even their tracking details is not showing any update after 09 May 16 on which day my parcel is showing reaching Delhi. Courier detail is Amazon Transportation Services, Tracking #:[protected].
Kindly take an immediate action on my issue, as after a regular attempt of more than 2 months i was able to place order for this mobile.
With thanks Regard's
