Airtel — process my refund for failed transaction

Hello, i'm using your network (4g pack) for the last 10 years. I have recharged for unlimited pack amounting to inr.598 through online on 14th apr'2020. The transaction was failed but the amount has been deducted from my bank a/c. Till date it has not credited back to my account. Once the transaction is failed you have to proper steps to refund that amount. 7 days got over till now and i'm not sure what steps you've taken so far. I'm losing my interest for these periods. You cannot expect the customer has to raise a query to you asking refund. Waste of my time and your time. Try to be a customer friendly. The details of the failed transaction status are mentioned below for your reference. Expedite your process.
