I have been writing e-mail since 9th of July regarding the bill amount of my mobile no.[protected], that I had already paid on 24th June which is not reflecting in my account. I had even submitted the credit card statement reflecting the payment. I had written to billing department, nodal officer, appellate authority, visited the airtel store 4 times, still the line has been Disconnected since a week.
