*********** Horrible customer service ******** I have used Viator for several tours and for the most part the tours were good and the tour companies have been professional. Buyers should beware- if you are buying with the impression that you will receive customer service if something goes wrong, Viator is not the company to use. On a recent trip to Rome, we bought the fast pass for the Vatican. The meeting instructions were poor and when we found it the tour company left and there was no one there to help us. We ended up buying a tour from another company. When returning to the states I tried to rate the experience but found the tour did not show on my bookings; I called Viator to get it added to my bookings and I got the run around. I tried for over a week to no avail and when I asked for a supervisor the customer service agent would not transfer me, place me on permanent hold until they disconnected or say they would call me back. I agent would not listen to my concern and just kept reading off a script.
