Flipkart — One Item out of two not received

I have ordered 6 sarees (ORDER ID - OD[protected] on 3rd October 2021. Out of which I received the delivery separately as follows.
1. Packet containing 1 Saree
2. Packet containing 1 Saree
1. Packet containing 2 Sarees
Then I was waiting for 2 more Sarees.
A packet was delivered on 10th October 21. I have received a packet on which there is a printed sticker mentioning the following two sarees whereas when the packet was opened it was found that there is only one saree in the packet details given below:
1. SAARA Floral Print, Printed Tant Cotton Blend Saree (Cost Rs. 524/-)
The following Saree, I did not receive.
2. SAARA Paisley, Woven, Embellished, self Design, Banarasi Pure Silk, Jacquard Saree (Pink) (Cost Rs. 2249/-)
I sent a detailed email to [protected]@flipcart.com as below:
Please note that the delivered packet when opened, I found that only saree No. 1 was there and saree No. 2 was not there. The packet was also small. You can send your representative from Nagpur to inspect the packet and check it.
On October 8 a packet from the same order containing two sarees was delivered, which was much bigger in size than the packet referred to above.
I called several times. I received four calls from them, every time I was required to narrate the story to a new representative.
I also received an email from Flipkart stating that my issue will be resolved by 16th October. I am pasting their message below.

I again called them, as usual, this time a new representative listened to me and promised to resolve the issue. Nothing happened so far.
I am a regular customer of Flipkart for many years. Such a thing never happened.
Please help me in resolving this matter so that I get my refund of Rs. 2249/- as soon as possible.
