[Resolved]  Airtel Broadband — Overcharged for internet usage

I took a new airtel broadband connection, with a download limit of 4GB on my account. After getting the connection, I was informed by the customer care that I can monitor my download usage by registering online. While I registered online, I couldn't see my usage. When I called up the customer care they informed me that this facility is available only after the first bill is generated. On questioning that how will I know whether I have crossed my 4GB download limit they informed me that I will get an SMS alert on crossing my limit. Since I neither got an SMS alert nor was I able to see the usage online, I continued using my internet assuming it hasn't crossed the 4GB limit. However, the first bill I received claims my usage at 6GB.

I registered a complaint for the same, and even after 20 days they issue is not resolved. Now Airtel says that I will have to pay (enen though one of the escalation managers I spoke confessed that it is a mistake on their side), since they do not have a process for bill waiver. If there is no way for the customer to know whether he has crossed his download limit then how can they charge the customer for crossing the limit. I am certainly not willing to pay for lack process in Airtel for bill waiver when it is clearly due to mistake/miscommunication from their side. However, at the same time I am afraid that I will lose the connection since I am not willing to pay for the overcharged amount.
