Flipkart — Flipkart did not refund my flight cancelled amount since 11 months

Address:

Flipkart Internet Private Limited, Buildings Alyssa, Begonia & Clove Embassy Tech Village, Outer Ring Road, Devarabeesanahalli Village, Bengaluru,

In the month of October 2021, I booked a round trip flight for 13 jan -17 jan 2022 BANGALORE TO PORT BLAIR & VICE-VERSA via flipkart. Full amount was paid through my sbi credit card.
The return flight was cancelled by indigo airlines 1 day prior to journey i.e., 16th Jan 2022. I received the credit shell certificate on 20 January 2022 via email from indigo airlines.
In may 2022 when I tried to book my upcoming flight through that credit shell, it was'nt successful so I called indigo airlines customer care, they told we already transferred full amount to flipkart, so i emailed and call to flipkart customer care multiple times even cross-checked with my bank also.
I called flipkart customer care then they assured me my full refund of
Rs.10236 will be process to my sbi credit card(original payment source) within 5-7 days. but Money wasn't reflected in my account. The same follow up procedure is On till today.

They asked to share the bank statements, email proofs from the bank that they haven't received the money in original source etc., we shared with them to verify but no fruitful revert from the Team.
Later they asked to share the alternate bank account details to process the money but nothing received till 7th nov.

I had several email and phone conversation with them but they still not refunded my money yet, it has been about more than 11 months.

now flipkart customer care team is not responding to my emails.

please take appropriate action against the flipkart for this wrong practice.
