The best I can give you in the way of an update is that my account has been credited for the overcharge. I went by my bank on Wed to make sure that everything was progressing account-wise, and it was. I did give the full story to the customer service guy (didn't talk to the bank VP, btw--he was with someone). When I got to the part about charging the card w/o my knowledge, I got the raised eyebrow. When I told him about her calling the bank & not knowing if she'd called my bank or hers, he said she might have called the one who handles her credit card transactions (this makes sense to me--they're the ones who would put the initial charges through).
I've still not received copies of all the receipts, as was promised. If they'd been mailed on Monday, they would have been here by Tues, Wed. at the latest. If they don't arrive in tomorrow's mail, I'm calling and asking for them again--and will add that if they haven't arrived by Tuesday's mail, I'm calling the BBB and filing a complaint. Yes, the financial aspect of this issue has been resolved, but she did say she'd mail me the copies of all the receipts. Those should have gone out in Monday's mail.
