I booked a motel room with trip.com for May 28-29, or so I thought. It was non-refundable. The calendar defaulted to June 7-8; I apparently accidentally booked June 28-29. Realizing my mistake, I called them within 5 minutes to explain and ask if I could change the dates. First, I called the motel and was told I had to change the dates via trip.com. Trip.com said they would have to negotiate a change with the motel. I called back three straight days and they kept telling me that they were not able to get an answer from the motel. Meanwhile, one day into the ordeal, my wife called the motel directly and got a reservation in 5 minutes' time! Finally, the date passed with no apparent REAL attempt on their part to rectify the problem. Admittedly, I made a simple mistake, but their response was dismal-the worst customer service I have ever experienced from an online booking company. I am only giving a one star review because zero stars is not an option. On top of everything else, I booked a room with 2 queen beds and they booked me into a room with a single king bed.
