Thanks for the link and address; I'll try them, too.
My bank, Chase, is not at all helpful about this (a debit used as cc purchase). They issued a credit, then took it away! They have "no record" of receiving the first TWO faxed e-mail copies, or the forwarded e-mails from bookin (promising me a refund). I also had a Chase person's e-mail who has not answered a single e-mail I've sent her. Every time I talk to a human, they seem increasingly stupid (now, start from the beginning, including your account, cc, SS, and claim numbers, etc.). (When this is resolved, I might have to switch every account to a different institution.)
