Airtel — airtel office

On the payment of my airtel postpaid bill, i did not receive any acknowledgement slip, as the employee on the desk said, i will receive an sms confirming the payment. The complaint is about the same as i never received any such sms and further i am being forced to repay that bill again.
Please look into the issue and resolve it asap. Hoping to see the details of my payments with the acknowledgement slip on future payments too.

Thank you.
