Flipkart — Flipkart refund amount not yet credited to my bank account

I had recently ordered an item from Flipkart on 05/01/2025 which was cancelled from the seller end on 05/01/2025.
The Refund was initiated and show's status as "Refund Completed" on 10/01/2025. But the Refund amount is not yet credited to my account. I tried contacting Flipkart Customer care But they were of no help, They wanted me to verify with my Bank with the 23 digit refund reference number that they've provided. I did so, but the Bank needs an transaction id, which is of 12 digits to verify the above. But Flipkart customer care gave me a 23 digit refund reference number which is of no use for the bank and the bank is saying that the reference number is invalid, my bank is SBI. I contacted Flipkart again asking for the 12 digits transaction id. But they say they don't have a 12 digit number and asked me to contact the bank again. I'm stuck in this loop between Flipkart and bank and the issue is still unresolved. I don't know what to do Further please help me.

Please help me, 23 thousand is a lot of money for me, kindly help me in this situation, i am requesting everyone.

I'm attaching the Screenshots of my Flipkart's reply
