Airtel — No intimation on bill amount and worst customer care service

Address:

Bangalore, Karnataka

I am having a post paid data card [protected]. I was getting only 100 Rs per month as I was not using it. And I was getting mails and sms regarding bill every month. Till April 13th as per the SMS received from Airtel my outstading amount was 224 + data usage of 300 MB exceeding the lower limit. ie. 224+Aprils 100+April 300MB = 500 Rs approx. And I removed the sim from my Tab to avoid extra charge. But unfortunately AIRTEL DID NOT SEND SMS /Email regarding the bill and I thought it wont be more than 500(outstanding). Now I have received call from Airtel and the bill is 1300 Rs. I came to know that April bill alone was 850 Rs. I am not sure how is my April bill 850 when i stopped using it when I exceeded by 300MB??? Why did not I get SMS or email from the month of April to intimate me regarding bill? How would I know that bill would be 1300 where last outstanding was jst 224? Dont you thin its your responsibilty to remind the user about the bill? Please revert as soon as possible.
