[Resolved]  Vodafone Subcriber — deduction of Rs.30/-for caller tune not used by me from my prepaid account

I am using Vodafone Services for last 3/4 years. The Services are
LIFE TIME FREE INCOMING..aS & WHEN NECESSARY i RECHARGE
the cell because now it is free roaming.From the 1st day of the
initial charging I have selected the caller tune available free with
the cell charge. For so many years Vodafone never charged for the selected tune.However I have received a MSG a week earlier
mentioning Rs. 30/- has been deducted from my prepaid account
towards caller tune.and the next rental is due on 27th Sept 2008.
The Message Centre No. [protected] keeps on ringing & no one
attends my call.I wish Vodafone should refund Rs.30/- deducted from my prepaid and not to deduct any further.I wish you will help.Or should I approch the consumer court& challage.Regards

Please acknowledge and advice.
