I don't know where he goes to get more money put on the card. I'll ask him, though. I'll also ask him to dig up old receipts (providing he still has them... I *think* he shreds stuff like that and since he no longer has to pay income tax, I can't think of any reason for him to save them.)
Well, with a little bit of luck somewhere along the line, maybe it can be salvaged! I hope so, for your dad's sake. Evildoers usually get tripped up.
