Airtel pre-paid mobile service
Disturbing advertisements

Disgusting advertisements in Airtel prepaid service, which can't be stopped:

I receive hundreds of disgusting advertisements (calls) in my airtel prepaid mobile connection. I have never subscribed to any such option. I tried to cancel this by sending SMS to customer care which always bounced back. Customer care was of no help at all. This is utterly disturbing and I believe illegal. Airtel is not taking any step to redress the problem.
