Viator.com pls beware of these peiple... huge travel agency but zero professionalism.... On our trip to Florence we did a huge mistake of booking online Uffizi gallery tickets with them. They not only cancelled the tickets without informing us and we sat in front of the gallery waiting for the guide to arrive but the number and office address mentioned on the ticket were both fake. When we contacted the customer care they simply tell us that the tour was cancelled. Easter holidays so we werent able to get direct tickets so we asked them to compensate by giving us tickets on some other day of our trip which they agreed and told us that they will give tickets for 2 days later booking. We extended our stay accordingly. We recieved an email too for the same from them. On the day of booking till 8am in the morning we did not recieve any tickets... We called them back. So they once again told the tour is cancelled. Pls note we called them atleast 20 times on international roaming. Now they say they will only refund the amount we cannot compensate u for anything else. The most UNPROFESSIONAL, CARELESS, company i have ever come across. If you want your trip to be memorable and complete NEVER book with them. They have no rights to be part of tourism industry if they dont understand that the travel experience and time both are precious and they just cannot go ahead and ruin it for their customers!!!!
