First they got my name wrong on my tours. They were contacted about this and I was informed that the trip to Machu Picchu and rainbow mountain in Peru sells out and they would have to cancel it and try to rebook and they didn't know if it would be able to rebooked. They told me to just leave it as is and all will be fine. I stupidly agreed. The day before the tour I had not heard about a pick up time or any thing at all. They probably could not contact me because they were looking for a person that does not exist. The real problem occurred when I now call viator they will not help me nor tell me any information because I am not the person listed on the tour. I gave them the credit card number used to pay for it, which is in my name. They said it was the right number but they have it with the wrong name. yet it appears on my billing statement with the right name. Argued with them for hours in my hotel room in Peru with no results. The most ridiculous customer service I have ever dealt with. Would not even try to help me. Just said they would have to launch an investigation. I will never use them again. BEWARE!
