Airtel data card
Internet connection is not happening

Please note it is more than a month that I bought internet 3g datacard connection but still am not able to connect to internet.

It is Linux OS and the airtel applet says that is has connected but the browser says page load error and address not found.

I have not browsed even a single page on my Desktop even after a month.

Airtel customer service hung up on me more than once.

Can anybody from airtel call me after 9 pm so that I am at home and resolve this issue.
