Airtel — balance deduction for airtel hot chillies service

Address:

605004

I got a message from airtel saying thanks for subscribing to hot chillies service for which i did not subscribe. My balance got deducted for rs 50.
This is not fair. Airtel should not deduct balance without user consent. All the services should be manageable through the airtel portal and each and every deduction should be traceable. This will severely damage airtel's reputation. Kindly do not do such things in future...
