Airtel was one of my favourite mobile network operator intially . but they are only I market to loot from innocent people in the name of their so called 4g net service. they charge 450rs for 2gb mobile internet which is not feasble for college students like me. . they randomly activate any service n deduct money from your balance. if you complain then they will give you some excuse n say it will not happen again.but, this never stops.
