I booked a Rome tour through Viator for my family of four. It was quite expensive. I went to the Viator web page and found a tour on June 17th. When I went to purchase it, the web page said that particular tour was sold out on that day, but "here are some similar tours that are available on that day". So I clicked on one and purchased it. Somewhere along the line, Viator's web page changed the date to June 4th. As soon as I received my confirmation email I contacted Viator and explained their mixup. I requested they revise the date to June 17th as I had entered into their system. This was literally within a few minutes of placing my order. I was told that all sales are final, no changes, no refunds. I proceeded to spend the next six hours of my European vacation with numerous Viator support people and supervisors trying to rectify their mistake, to no avail. Viator tried to wash their hands of this saying that it was not their responsibility and that it was in the hands of their third-party tour operator. This is not true, because I purchased the ticket from Viator's web page. They sold me this product. This has left me with such a feeling of being robbed. I'm out over $600 and received absolutely nothing in return. It is worth noting that I never entered the Date June 4th. The only date I entered into Viator's web page was June 17th. I was scammed! The simple correction I require is for Viator to honour my request to change the date of the tour to June 17th - as I had entered to start the process. Date of experience: June 04, 2024
