Amazon India — Not delivering the item by saying Illogical reason

I order 3 items on nov 1. Orde ID[protected].
Payment was made by credit card and product shipped fastly. But at the date of delivery, they returned the product without my consent. I didn't even recieved any call from the courier service. They are saying the address is not deliverable area. When contacting the amazon customer care, they said the address and pincode are not matched. Big LoL. Who else know my accurate pincode and address better than me. And the biggest joke is that amazon delivered few items to that exact address weeks ago. I asked the customer care to google the pincode. The whole area was under that pincode. And they understood and reported that issue. They also promised me i will the 2nd item on tomorrow itself. That night again i contacted them and they double guaranteed me the delivery next day.

But the same thing happened to the 2nd item. It also returned without any message or call. I told them many times iam ready to collect the it from their hub. Was raised my issue with them. They suggested me the replacement option. I agreed to do so. I m not sure about the delivery anyway. At least they should change the courier company.
They are simply wasting my time. Was really excited to collect the courier on that day. They disappointed me.
3rd item is on the way. Have no hope for the delivery.it will also return without any information.
I think they are not trying to deliver the item. When offer ends, i have to pay the full amount.

Order ID of item which they delivered to exact address:[protected]
