Did not know Tripadvisor and Viator are same company, thought i double booked a cooking class in oaxaca so i cancelled Viator, then saw the class was cancelled on Tripadvisor as well, googled and discovered they both are one and the same companies (i have both apps) anyway, within 15 min I realized this error, contacted viator through chat, explained I still want this class (5 months away) $115 USD already taken off credit card. I asked to be put back in the class and Viator told me no putting me back in class, no refund that's it. Wow! 15 minutes later and 5 months away!! They said they would re-book me for another $115!! Will dispute this on my credit card, but be wary other consumers out there. Once Viator/tripadvisor gets $ for event, you will never see your $ again no matter what.
