Amazon India — amazon.in forcefully merged my two different orders in single order and force me to compulsory take both order or else both order will cancelled

Address:	Mumbai City, Maharashtra, 400084
Website:	www.amazon.in

I HAVE ORDER TWO DIFFERENT ORDERS ON DIFFERENT DATES FROM www.amazon.in.

1ST ORDER DATED 22 January 2019 Redmi Y2 (Black, 4GB RAM, 64GB Storage)
Order NO[protected]
QTY -1
PAYMENT METHOD Pay on Delivery (Cash/Card)

2ND ORDER DATED 20 January 2019 Redmi Y2 (Black, 4GB RAM, 64GB Storage)
Order NO[protected]
QTY -1
PAYMENT METHOD PAID BY CREDIT CARD

As I give all details of two orders that made on different dates and both orders no’s also different
One order was COD and One Order was paid by Credit Card
As mention, I expected that two different orders should be treated as two separate orders. And should not have any connection or any dependency of orders on each other. But due to some personal reason, I want to receive only paid order and want to cancel my cash on delivery wala order. (you can cancel cash on delivery wala order at time of delivery also without any charged)
But while delivery Amazon.in send me both orders in the same shipment. That not issue.
The main issue comes here that Amazon.in merged my both orders as one order and send me in single shipment box and said that "you have to take both orders from us, you cannot get separate items", as my orders was both separate, on different dates,
And "if you cancel one order then automatically second order will cancel by the system" .
For that purpose I have called customer service desk but no resolution. They said clearly that "we cannot do anything from here". They accept that the issue is in system but they cannot help me out for that.
I said them "if order two different orders on a different date and I have not order as bulk quantity, That was the single quantity in single order then why amazon.in guys merged my both orders and made as one order. And trying to force me to sell both order, as I don’t want CASH ON DELIVERY order, I want only order that I have paid for you".
But they said "I cannot help you in this, either you have to take both orders or if you cancels one, the 2nd order will get cancel automatically". repeatedly saying this
My clear question is that. "If I have ordered separately then why amazon.in merged my both orders as one and why I should forcefully take both orders, not a single order" .
That’s the harassment from amazon.in to me
Customer care also not supportive they are repeatedly telling that we cannot do anything from our side.
In this case clearly showing that amzon.in faulty and they cannot force me to take both orders or forcefully cancel my both orders, as both are separate orders should treat as separate not as a single order.
I need my paid order separately not a money.
Kindly help me out for that. Thanks.
