Consumer Redressal

For 1 GB I am charged for Rs. 98.00 and for another 1.28 GB I need to pay almost Rs. 5000.00.Does it make sense for billing exorbitantly high? It is commercially not justified either. Pls. expalin ... I get message for every 200 MB used but I did not get any message after 1200 MB usage...Pls. explain why? On 27th of August 2013, I got a message that I have crossed billing of Rs. 9000 which is my existing credit limit so I need to pay interim amount to be accessible for data services and by late evening Data Services were disconnected without giving me any time.Moreover, next day I got a message that my billing amount for the month is Rs. 5206.37.If that is my billing amount then why you have deactivated the service which is below my credit limit. Pls. explain why you have not deactivated the Data Service when it crossed the limit or you were waiting to get money from the subscriber in another way. I was expecting many important mails to receive and send these days being month closing w
