Airtel — inspite of charging the phone for rs 448 we have not received the service

Address:

683514

Sir,
I had charged my mobile for rs 448 today for which i received a message saying service has been initiated and the txn id for ref[protected]. My account balance says rs 18 only. I tried to use the net services that too did not work. Could you please do the needful. This is the second time i am facing such an issue again.. Hope in future this would not be repeated.
Regards
