I bought some goods from Louis Vuitton L.A with a Natwest Visa Credit card; and returned the goods one and a half days later, as they were misrepresented to me. I returned them at the Louis Vuitton S.F store. I was refunded the full amount in dollars - and hold the credit receipt. My bank telephoned me a few days later, and was very surprised that I there was a difference, shown on my accounts, between what I'd paid and what I'd been refunded during that transaction. This is where I'd learned I had NOT been refunded for the conversion of currency, which amounts to £200. Is this what usually happens when a foriegn credit card is used to purchase/ refund goods? Is there anything that can be done to return the price of the conversion? Thank you very much for your help!
