Recently my postpaid bill is generated for my IDEA number 83********
Normally i receive 299 rs bill but this month I was charged 2508 Rs.
While checking the bill I was falsely charged for 330 International messages which I did not even send from my mobile number.
I checked my mobile and there are no SMS sent at all to those numbers.

As the customer care people wants me to pay the bill.

I don't know anyone out side india and I don't have a need to send 330 messages.
I will be paying only for the services which I used and I want IDEA to reverse the charges which I did not use.
