I would like to see a complete and detailed of all transactions related to billing. In one list, one location, in one view. All top ups (+), all SMS/MMS charges (-), all monthly charges (dedicated number) (-). Basically, when I look at that list, it will explain why my balance is $-3.75. Right now, I looked at my top-ups, I added all SMS/MMS charges, added all monthly charges to check. I shouldn't have to do that. All of this should be visible from the billing page.
