Used booking.com to book a room at the Quality Inn Merchants Drive in Knoxville, Tenn. Their promotion clearly advertised free cancellation and pay at the property. My confirmation came back with a $189 cancellation fee if I cancel the room. Some days later my card was charged $220.30 for the room. I am sharing the room and did not want to have charges on that card. I only used it to hold the room. Through slow correspondence, I was finally informed that the room cost more for free cancellation. I never saw that option. But I can live with that. I responded asking about being charged for the room. It's been a week and I have had no response. I will never use or recommend booking.com again.
