Partly, so we could book a Viator tour of Buenos Aires before our cruise, we arrived there one day early. Having been robbed twice in that city, we didn't want to venture on our own.
We booked the afternoon tour, since we wouldn't arrive in time for the morning one. At the hotel, we discovered that they had messed up the time, and the tour had come for us that morning! I spent three hours on the phone between Viator and their local tour company (mostly on hold) trying to get them to come for us that afternoon. Neither party agreed to help us.
So it was basically a wasted day. Equally infuriating was that Viator told us we should have made a long distance call out of the U.S. 4-8 hours in advance (while we were flying) to verify the tour, in other words, to make sure they hadn't canceled the tour and not informed us!
Viator offered to do nothing for us but refund our tour price, not even a future discount. No company that values its customers would refuse to offer any good faith compensation whatsoever!
