Airtel — lifestyle services

This was the second time i got charged for some lifestyle services of airtel. I don't even know what is lifestyle services and when did i activate this? First they charged me 15 rupees and after that i didn't recharge and today i recharged now again they have charged 15 and i had 15 rupees only. And right now i'm running out of balance. I requested to stop but did not get the money back and they just stop it for a while and again after few days they activate it again this is so disgusting.
