First, thank you for the recap and explaining the situation to the manager. I wouldn't have been able to negotiate the situation without your help. I do think the manager was being accommodating, but there was really nothing that could be done, so we had the manager void both transactions.

Here are the two charge attempts and corresponding void slips:



I checked my online account, and the void charges are there too:



The DCC markup is 4.2% above the Visa rate. So our 565.00 HKD transaction was quoted with a DCC amount 75.92 USD. Using the October 11th Visa rate the, the charge should have been 72.86 USD, so the difference was 3.06 USD. We made the executive decision to have percysmith make the charge in his card denominated in HKD. I hope cxua can pursue a successful chargeback and that Chase follows through, but I have my doubts that they will with such a small difference.
