I purchased tickets for an event with Viator. Credit was used to purchase them. Received confirmation from Viator. When I tried to retrieve the tickets. I received a message that order was canceled. Viator never contacted me to let me know that they canceled my order. I called my credit card company and they stated Viator charged the card, but then canceled. I called Viator to see why they canceled and was on hold for a very long time and they never got back to me. Very disappointed in Viator. I had to call other companies at the last minute to purchase new tickets.
