Airtel — airtel prepaid recharge not done but money deducted

I have recharged my airtel prepaid number [protected] in airtel.in website on 14/4/2020 for the recharge amount 149rs. My money got deducted but recharge is not done. Even the refund is not been done, it's more than 2 weeks of time.

As the recharge got failed i have tried recharging it again the same day, and it got successful.

Please refund the amount which got deducted in the first attempt of recharge.
