Idea cellular has charged excessive amount in the aug bill. In the bill details in so many calls only my own no. is mentioned. Is this possible that someone can call himself from his own no.

Second thing in so many calls they have charged without mentioning no. I am trying to sort it out from last 10 days but everytime person from Idea say that we will sort it out but nothing happened till now. Tomorrow is my due date.

I am really fed up now and doesn't understand what to do? Could anyone help me out?
