i am using airtel postpaid connection last month i activated 3g plan 750 Rs 5GB data usage. airtel is not communicating for usage qty of data..

instead of 5 GBwithout knowing used 5.7GB. for this they charged 4650 Rs around.

when i called airtel they r answering like morethan 5 GB they will charge huge amount only...

if i am using more than 5GB i am expecting that they have to stop service or i need to get msg that i am crossing the limit or plan has to change to next level

but here they cheated me for money... how to live with these type of people

pls help me on this
