WTF is wrong with NRGi (my electricity provider).  Did they just get a truckload of electronical transactions with a best before data in a week?  Why, og why, would anybody even consider making a DKK 0,00 transaction?  Who approved the system that thinks this is a good idea?

The positive and negative transactions sort of not-really make sense (the positive one is some cash-back which obviously cannot be coordinated with the negative payment for electricity).

Edit: The idiots even sent me a letter concerning the 0,00 payment (electronically, but still fairly expensive):
