Airtel — unsuccessful recharge but amount has been cut

Address:

Airtel company

Dear airtel,
I want to put to you notice that i have recharged an amount of rs 449 from the airtel app through bhim app. The money has been deducted from my account but recharge wasn't successful. I haven't received any message regarding this nor got the refund back. Please look into the matter and refund the amount as soon as possible.

Yours sincerely,
