Airtel — namkeen pack deducted money without concern.

Address:

506001

I got a message from airtel on 13th feb 2018 12:52pm mentioning that namkeen pack services has been activated on my phone for 1 week and they would be adding rs 35 in my bill for a week and this would be automatically renewed every week. On calling airtel, to know what the service is all about becuase i never raised this activation request, they are saying that they dont have information about it as it is 3rd party service. But i got the message immediately that they deactivated it. I really dont understand that how come airtel does not information about the service they can activate or deactivate. They say that i would have clicked on an advertisment or something and the service got activated but airtel has no information.

My concerns are
1. What is that service all about
2. How did the value added service got activated without my consent
