Airtel
Balance deduction

Hi

My mobile no is 9934785575.I have recharged my mobile with internet pack of 98.But they have deducted money from my main balance for the internet uses after recharge. When i call the customer care, they suggest me every different ridiculous reasons for that, every time i called them and disconnected the call. After 8-9 try one of them finally checked the details and assured me that money will be return in 1 hr. After 2hrs i connect again and they say it will take 4 hrs. Now its 15 hrs from that time, and i still not get the balance back.
