Flipkart - Mobile not delivered on exchange

The second time the same problem happened.
On the *th of July I have booked a Redmi Note * Pro (Neptune Blue, *** GB) with order no:
OD************** on Flipkart with Seller: SuperComNet and by paying ₹**,***.** (Actual Price ₹*****.**) with an exchange of my old mobile with an exchange value of Xiaomi Redmi Note * IMEI: ****************** ₹*,***.** and pick up charge ₹***.** from Flipkart and was expecting its deliver on *th of July ****.
I got the call from the delivery boy on *th July for the delivery of the same which I rescheduled for *th July ****. Upon his arrival, Mr Naresh from Begumpet rejected my exchange mobile and left my place without giving me the handset as per his exchange policy and even after me offering him cash as per the Flipkart policy to buy the phone by paying cash if exchange rejected and advise me to contact the customer service of Flipkart.
Below is the conversation with Flipkart which I did for the exchange of my old mobile. On *th of July ****, upon contacting the Flipkart they requested me to send the photos of my old phone as per the guideline they send which I did.
On the *th of July ****, they emailed me for the acceptance of my exchange as per the images I have sent. If any changes then I can pay **** and collect the mobile.
I received the following message
