I enrolled in FedEd's online bill pay, so I don't have to worry about getting bills in the mail every month. My first payment was due a couple of weeks ago, so the week before, I called to double check that everything was all set up. "Yup, you're all good. This is a great service, you'll never have to worry about a thing!"

Cut to last night, I get a pissy form letter from FedEd informing me that I am past due. Of course it was on a Friday night, and of course they're closed on weekends. I can't do jackshit about it until Monday.
