A hotel wrongly charged my credit card (for mini-bar items I never took). I emailed them and they refunded me. Only they refunded me a smaller amount than the initial charge. I expect the difference comes from currency exchange fees and/or actual differences in exchange rates between the date the credit card was charged and the refund.
It seems strange to me that I end up losing money due to charges that I never consented to and they had no legitimate reason to make. (Even if the exchange rates could perhaps also have worked in my favor, I never consented to making this gamble.) Do I have the right to get the full refund including these fees and/or changes in exchange rates?
(The hotel was in the US, the credit card used was French.)
