Address:	600118
Website:	www.vodafone.in

I've been using Vodafone prepaid sim for a year or so.And this is the third time this is happening.I got a message that I had subscribed to Social Book service and deducted 90rs.I didn't subscribe to anything.This message shows up automatically and gone is my balance.And they really had something called customers care, they should have atleast sent a message describing the features of the subscription.Someone should sue them.Should Port my number soon
