Dear Roe,
Thank you for the peace of mind about the credit card! I haven't yet heard back from Visa, and even if the request is turned down it wasn't too much money lost, more like principle. But thanks for your message, it made me feel better.
Thank you also, Mongo! While I'm not glad to hear of their agressive employees and that other people have been treated in the same manner we were, I am glad to be backed up a little and to know we weren't the recieving end of some isolated incident or bad joke or something.
Thanks to both Roe and Mongo for sharing their helpful experiences!
Danielle
