Airtel — Failed Transaction[protected]

I have done my mobile phone recharge (Airtel) on 9th June 2022 for Rs.99 around 12:35. I have received the message stating it will be processed in 4 hrs. But the next day i have received the message stating it is failed and refund will be processed in 7-10 business days

Its been one month now, I have not got the refund. I reached out to Airtel store Koramangala they say transaction as not happened and they cant see it. I have sent email to Airtel but there is no response. Being customer of Airtel for more than 10 years i have lost the value and integrity for Airtel not resolving the customer issue.

I am getting in touch with the bank but they need the statement, how can Airtel can share the statement i am not sure, Airtel does not even confirm that the transaction is failed over an email.

I am stuck. Kindly support and resolve my issue. I can share my mobile number, but using the failed transaction id[protected]) you can be able to process the refund.
