Is there any way on Prepay to see a history of calls/texts made/sent? My wife has a query about her charging (she seems to be being charged texts/calls to me, and I'm set as her Bestmate). Sadly the Vodafone website doesn't have a "see history" button or anything like that. She had credit this morning, after texting me it was gone, but it should have worked as a Bestmate charge (ie, free to me).
