Airtel — Money not refunded back

Address:

Central Delhi, Delhi

My father is airtel postpaid customer([protected]). I paid the bill of Rs 775.82 for March billing cycle against the same. This bill amount is now added back to my airtel billed amount and I got the message on 21st June stating that money will soon be refunded to my bank account. I paid this bill via axis bank debit card. Till date(27th June, 2012), the money has not been credited back to the bank account. Moreover, customer care executives were not able to resolve my query. Further, the advised me to send a mail to nodal officer. I have also not recieved any communication from nodal officer although I sent the mail to nodal officer several days back with the bank statements attached.
I need to call complaint helpline(198) almost everyday and put my call on a long hold. Its disgusting and not at all accepted from a brand like Bharti Airtel. Why should I bear the malice?
Just reply asap how long would you take more to refund my money. And if you are not willing to do so, then I need to file a consumer forgery case if my complaint is not resolved by tomorrow. I will not tolerate this now and will not pay any further bills if my money is not refunded.
