Vodafone — Discrepancy of bill and deactivation of sim without any prior warning

Address:	Pune, Maharashtra
Website:	vodafone

My sim card has been deactivated because of due bill payment of RS.2500 for 15 days. They have claimed that I have used 3GB 3G data but in reality my mobile shows that i have used 1.64 Gb data . In Plan wht i used i had 1GB free and after that i have to pay for 640MB which i was earlier told that its 2 G free. and they now want me to pay the bill amount for the data which I havent used..And they have just deactivated my sim without any intimation. I have seen many complaints on the same page regarding the same issue that i am facing.I want you all to take some action.
