Vodafone — Fraudulent charges through wrong information

I was using a zero rental plan for Vodafone -GPRS. I needed GPRS settings for a new handset for which I called Vodafone Customer Care(111) and they fraudulently asked me to send a message to activate a Vodafone Package instead of the correct message for the GPRS settings. I realised the fraud in my last bill and stopped the service but they have charged me again for the whole month since I had discontinued the service during the beginning of this billing month. The customer care I spoke to in February confirmed that the Customer Care executive had given wrong information, but the one I spoke to today (Virendra[protected] rudely said it was my mistake.
