Airtel — incorrect billing by airtel and wrongly billed huge international roaming

Dear all,

I want to warn all airtel users on their incorrect billing charges. I've had airtel services since march 2008 and have been in usa on an overseas project from may 2014 to current. All was well, until suddenly for the month of july, airtel billed me an excess of rs. 18000 in international roaming charges!
It was futile to speak to any so called "customer service representative" and several supervisors who parrot a standard preset reply, stating they are correct.
In my case, i used it only for incoming sms for otp for online banking transactions. Period. At all other times it was left unused and sometimes even powered off, so their claims on data usage are completely hollow.

So, it was ridiculous for them to charge for a month while i've been in the usa over 4 years with local usa land lines and mobile connections.

Beware, of airtel false billing and their metering system!

I'm done with airtel and disconnecting my airtel service with immediate effect.
