I booked a tour to Rainbow Mountain months ago. Money was withdrawn from my account. I wanted to make sure with the travel company the day before my trip. I contacted Viator app. The tour operator did not respond to anything, I also called, there was no answer and the line was not working, it went straight to message. I contacted Viator and explained the situation, it does nothing but sends emails. On my trip the next day, it just sends emails to the company. I woke up early at 4.30 in the morning, I waited in front of my hotel in the freezing cold but no one came. My hotel booked another trip and I only went to Rainbow Mountain the next day. I went to the company address on my travel day with Viator, but there is no such company at that address. I asked everyone there, no one knows the company. Viator works with this fake company and group that makes its customers miserable. I had to wait 72 hours for my money to be refunded. This is such a shame.
