I got DCC'd again 2 days ago in Glasgow Scotland. I took a tour of Loch Ness and the Scottish Highlands that was supposed to be for 40 GBP ($67.19 USD). They took my credit card over the phone (the driver called his tour office with my CC#) to pay for the tour & I discovered today they charged me $70.42 USD (41.92 GBP), an overcharge of nearly 2 GBP or $3.23. I called CapitalOne and they saw it was a USD/DCC transaction & gave me a courtesy refund of the $3.23 difference, however the CSR decided it would be best to still file a dispute as they should not have charged me USD via DCC without asking my permission. I'm guessing the tour office worker just automatically accepted the DCC without much thought or simply out of habit, resulting in this overcharge. It's very frustrating that these types of shady transactions are allowed to happen & disputing them can be such a hassle.
