I called into Chase's dispute line to challenge what was a $60 difference, and they initially disputed the entire transaction pending Conrad's explanation. When Conrad never responded, they voided the entire $1000+ bill.

From the information you posted, it sounds like Visa is taking a hard line in the customer's favor, and making it clear to everyone that ignoring customer's DCC choices would be unwise for the merchant.
