Seems like a major, major fraud to me. Far too many to be explained as an 'admin error'. Buying a list of 'legit' numbers is probably the most likely as from all the posts I've seen, there seems little correlation on usage. I'm surprised that they haven't been stopped ... maybe they have... Multiply the small number of 'erroneous transactions' here, by the big wide world, and we're talking some serious amount of dosh...
