Vodafone India — Vodafone Caller tune activated automatically

Address:

Chennai

Vodafone have automatically activated caller tune to my mobile number and deducted amount from number.
In reality never accepted /clicked or sent any sms to enable caller tune and
I have been charged for rs30 and there is no refund when i asking them to disable it immediately.

This is really unfortunate that vodafone is adding vas automatically and there is no refund on cancel request.

But i have not requested any such services to activate. So please kindly refund my amount asap.
