[Resolved]  Airtel Bihar — balance wrongly deducted

I on behalf of Surender Singh,Mobile No. [protected] state as under:
every month Rs. 249 is deducted for GPRS service while I have not activated the same. In november,2007 I got a sms that ur gprs service has been deactived. However, in december, 2007 the same amount is deducted and now my account does not show the balance. I can niether make call to customer care due to negative balance not send sms to customer service. this is very bad for bihar airtel service. kindly take an immediate action please because since february, 2007, my balance is deducted for the same but customer care doesn't respond properly. He always says that this service has been activated on your mobile on your request which is wrong. please take immediate action to refund my balance and to deactive gprs service.
