Airtel — hot chillies activated automatically

Address:

Dakshina Kannada, Karnataka, 574150

When i was browsing through web there were so many adds popping up in different tabs but i never clicked on any add ant whenever the add was popping up i closed it. After that i closed my browser and after sometime i received a message that the funzone and hot chillies service has been activated but i never activated it and the money was deducted from my account. Afyer that i deactivated both of the service and after sometime i again received a message the funzone has been activated and again my money has been deducted. I called the customer care number and she told me that i has been activated through the web. I never clicked on any add. What is wrong?? Airtel please help...
