[Resolved]  Airtel — customer service not reachable for a week

Address:

Pondicherry, Puducherry

I have a prepaid airtel connection.
On 9-may 2011, i got Rs.99 deducted from my balance. I got a message stating that they deducted the amount for downloading something, but the fact is i was not even using the phone at the time as i was travelling/driving. Im trying to contact the airtel prepaid customer care for the past 4 days, and their customer care number [protected] or 121 is not working.
Its a blunder that the nations largest telecom providers customer care number is not working for 5 days.
