Flipkart — Money Not Refunded for over 4 months

Hi team,

I wanted to register a complaint regarding two things:
1. A pending refund of 6k for an order which i will explain in detail
2. Bad CS experience where the above issue was highlighted multiple times and the Support Team keeps marking the issue as resolved even though it is not.

ORDER ID: OD[protected]
For this order the following things happened:
1. I placed an order for a phone motorola edge 30 which costs around 2100
2. I applied exchange for my old phone. The value came to 6, 350rs
3. This was deducted from the cost of the new phone which now came to about 14, 907
4. I made the payment of 14, 907 and waited for the new phone.

5. When the delivery agent arrived, he checked my old phone for any issues. There were issues and the final exchange came to only ~4k. I said to cancel the exchange since that was too low and ill pay the excess amount.
6. He cancelled the exchange and i paid the excess amount of 6350 thru UPI to the delivery agent. So the total amount paid is now 14, 907 + 6, 151

7. Then when we opened the new phone, we saw that the new phone had scratches. Since it was open box delivery, i cancelled the new phone. He said that i will get the refund.
8. I waited for a few days and got the refund of only 14907
CS Support
9. I filed a complaint with CS Support .
10. They made a call and i explained the whole issues. They said it will be resolved in 3-4days.
11. It did not get resolved but they marked the issue as resolved.
12. When i called again i had again raise issue, again explained the issue
I explained the issue toe 5 other ppl wasting my time each time for over half hour and all they said is that it will be resolved.

I still have not got the refund of 6, 350 and after raising the issue multiple times they are simply marking as resolved.
There have been 13 support tickets opened in this order. Still do not have an issue. I need a resolution for this asap as it has been over 3 months of dealing with people over a plain issue where i have all the details including upi payment details.
