Amazon India — order cancelled on delivery date for stupid reasons

Order id - order #[protected]

I ordered 4 books from amazon.in which was due to arrive on 5 january 2019. At first they only dispatched 3 books out of 4 and i had to cancel the remaining book that was bound to be delayed by them.
Then on delivery day when i tracked my consignment status, it showed returning to seller. After waiting fir such a long time, all i got was this stupid reason : "our delivery master do not deliver in your region".
Come onnnn...
I ordered it on 29/12/2018.
