Really, why, what evidence have you got?

A colleague in work and my sister-in-law have just found out they've
the same billing problem as me. I know it's not statistically robust,
but I've only asked 8 people to check if their meter units tie with
their billing units. That's 2 out of 8. I posted the original message
