Thought I had called the hotel I wanted to book. When I called them back to cancel, they said I couldn't cancel because I didn't make the reservation through them. And they couldn't tell me who I had made it through, either. They said I would be charged for the room anyway if I couldn't figure out who I had made the reservation through and cancel through them. Fortunately, I figured it out somehow and managed to cancel it. But I am very disgusted with the situation. I hope it never happens again!
