Fees for Hotel cancellation on credit card although it was stated that canellation was free

[BjoernEckhardt]

I accidentally booked a hotel for the wrong date and canceled the reservation a few minutes later. The cancellation was allowed and, according to the terms, should have been free of charge. However, I now see a small fee charged to my private credit card that I used for the booking. Does anybody know whats behind that fee?

@BjoernEckhardt it is possible that it was a booking fee from the travel agency, not a cancelation fee. That is what my guess would be.
