Airtel — Amount debited but no recharge reflected

Address: Kolkata

I made my Airtel recharge on their app via my sbi online banking yesterday morning but still there is no recharge reflected but amount got debited. I have registered my mail id in the app but whenever sending a mail to [protected]@in.airtel.com with my issue, it's replying that my mail id is not registered & asking me to call121 to register but I can't do it there at all. Please resolve the issue.

Regards
