Had a little hiccup this morning - a wire transfer that should have been made by the time I got up hadn't shown up, so I wrote the folks and they thought they'd paid it back on the tenth - but their system had put in the wrong invoice number into their computer, even though the wire on the tenth had the correct invoice for that payment. In fact, their system had put in two wrong invoice numbers for that payment, including one that's not even due for another two weeks. So, we got it all straightened out quickly as to what was paid back on the tenth and what was due today, and he got it done within five minutes, so whew!
