When you pre-pay for phone call credit, you are really just releasing some funds to your phone company to use. The same is true of my public transport card and store gift cards. This is what makes it all the more infuriating, to me, when companies decide that you've had long enough to use that money and confiscate it. This is routine policy in all the examples I've noted above. So what gives companies the right to take your money for the crime of taking too long to spend it? I think there's something deeply wrong there.

PS - I don't have a pre-paid phone, but I've had store gift cards expire.
PPS - That really should mean "refunded".
