Airtel — wrong deduction of my balance

Address:	New Delhi, Delhi, 110025
Website:	www.airtel.in

I am on international roaming. I recharge my mobile [protected] on 9 sept rs 300.
10th of sept they deducted 99 rupees for international roaming next day again i checked my balance and they deducted 30 rupees. Again i checked my balance on 15 sept and what i am seeing that they deduct 26 rupees again.
I am on international roaming i am not receiving any call i am not making any call nor sending any message. This is pure harassment of the consumer.
I need my balance back and i dont want any deduction in future.
