Although TourRadar provides fast customer service, they don't even know what they are selling, hence customer service is poor and superficial. I booked the Peru-Bolivia-Argentina tour for 7,500$. I am extremely surprised that nobody asked me what my preference was as to what was my for Machu Pitchu option. In the guide there are three options: 1- The Inca Train 2-The alternative 3-Train and was assuming that if 1 was not available then I would have option 2. They booked me for 3 without asking, and the intrepid guide told me that I have to pay extra for 2 to happen. they are truly incompetent
