Vodafone Prepaid — Alert service charged without my consent

Prepaid Vodafone No. [protected]

I have received an SMS from Vodafone mentioning that they have charged Rs. 30 for the `Alert' service and my present balance is Rs. -15. I have never opted for this service, and the Vodafone has activated this service at their own. When I want to deactivate the service I could not do so. I have talked their dealer as well as their customer care. The customer care is saying that they are not responsible for this activation when I asked to deactivate this service and credit the amount to my account. But he kept my call in hold for a few minutes and no response has received from them after wards. Now-a-days, the customer care is charging the call made to them.

Kindly take up the matter with Vodafone and ask them to credit the amount charged for `Alert' Service.
