Airtel Card
Deduction of balance

I been using the Airtel prepaid card and these Card i use only for the GPRS and nothing else. Once in a week i activate some time more than tat. The day when i activate the balance is deducted but tan too sometime double or more than tat its automatically deducted when i try to complain through customer care they talk so rude and make me confuse. Other than this yest i got a msg tat MCA is been renewed though i had sent any msg my balance is Deducted for Rs15/- and when i asked to Customer care they reply me telling tat they r not having such kind of information they reply telling to call after some days u will get the information.
