Airtel — Recharge benefits not reflected and no reply for request raised

On 4th of July recharged my number with rs 301, Amount deducted got message from bank with transaction ID and confirmation message from Airtel with Order ID. But benefits were not reflected. Raised request from Airtel mobile app but got ticket got closed not able to see any details like how they closed the ticket. contacted Airtel via customer care the only reply i got is 'Transaction never happened contact your bank'. I don't know how i got confirmation message from airtel if amount was never transferred.
