Reservations.com Beware of "Service Fees" for changing the pay method of reservation Orlando Florida

Made three on-line hotel room reservations for the Bonaventure Hotel.  First, I thought I was making the reservations directly with the hotel.  The search engine brought this web site up first and looked exactly like the hotel's real webswwite.  When booking, I inadvertently used a debit card to make the reservations and wanted to change the pay method (since they charge your card immediately).

Customer service advised since the debit card was already charged, I would have to cancel the reservation and re-book.  I was then told there would be a $14.00 "Service Fee" to cancel the reservation per their policy.  I feel very strongly this is a bogus business practice since their "system" does not allow for a change or reversing a charge transaction.
