Amazon India — non delivery of samsung galaxy m31 device

Address:

EA -5, 5th Floor, D Block, Tata Primanti, Sector 72, Gurugram 122101

I have ordered samsung galaxy m31 device, in exchange of a device, payment for which has already been made online. The delivery person came to my place on 15 sept to deliver the item. As the exchange device had to be given back after verification, it took some time. The person went away saying that he will come back after delivering another place within the campus. We enquired and requested him a number of times to come back and deliver the item but he did not do so. At the end of the day, on enquiry he mentioned that someone else will come the next day by 11 am. We have been waiting for the last two days but no one has come to deliver the device. No response from the person/amazon delivery has been forthcoming despite number of calls. Can we know as to when it will be delivered to our place.
