When I noted the reservation invoice for a Canadian hotel was in U.S. dollars, and excessive, I immediately called reservations.com, and was advised that the order would be cancelled and that there would be no charge on my credit card. I now find they put through a service fee. Not worth the hassle to fight it - but will never use their service again, and will tell others - "USE SITES LIKE THIS TO GET INFORMATION ON HOTEL OPTIONS IN A CITY - BUT NOT TO MAKE RESERVATION. PHONE THE HOTEL TOLL FREE FOR RESERVATION OR USE THEIR SITE". That way reservations.com gets exactly what their service is worth - zero.
