[Resolved]  Airtel — I need my money back immediately...

I did recharge through my mobile from my airtel app on number [protected].
The transaction was successful but recharge failed due to server issues. I got a message from airtel on screen, they will refund my money in next 2 hours. But then i received message on [protected] that i will get my money back within 7 days in my account.
First message :-
"dear customer, your refund for your recharge transaction on 25/06/2017 date has been initiated for rs. 549.0. The same will get refunded to your account in 7 days."
Second message:-
Your airtel mobile [protected] online recharge txn id [protected] of rs 549.0 has been initiated. Please keep the txn id for future reference.
Third message:-
We are experiencing technical issue at our end. We will refund or recharge with your selected denomination in next 2 hours. Regret the inconvenience.

I need my refund immediately... I am pissed off... I don't have much balance to play this game with airtel. Being your old customer i think i deserve immediate response from your side...
