[Resolved]  Idea Cellular — wrongly overcharged bill

I am using a postpaid card nd i have been wrongly charged with rs. 4090. H9w can i be charged so much when i didn't even use anything. This is so unfair. I want to know the details why am being charged so much without usage. I never expected dis from idea. I am highly disappointed. If it's really that much atleast give me details of what i used. I don't even call from dat number or use any internet or anything. Get back to me about this
