We´re a tour service provider. This company has a lot of problems even with tour service providers. On every listing site, my company has 95% 5-star ratings. On this site, less than 50% due mostly to Viator's bad policies. A few examples: 1. I permanently lost access to an email account I'd had for several years after following the instructions of 1 of their help line agents. This same agent made several other errors that cost us bookings and income. All complaints filed against the Agent were completely ignored. 2. They allow customers to lie in reviews. I literally have several official responses from their review team stating it's okay if customers lie in every other part, if even 1 part of the review has valid information. 3. Following several customer complaints to our company, We were given permission by 5 separate help line agents to do an experiment. All conversations were in writing. Every part of what we were doing was fully explained and we were told we could proceed, it was fine. Agents even sent us special links and provided special instructions to make the experiment go faster and more efficiently and effectively. Even though we were given clear written permission, their content integrity/reviews team later lowered our tour listing and threatened us with criminal charges for doing what their staff gave us permission to do and instructions for doing. 4. Many of their supplier help line agents are poorly trained and often misstate Viator policy(-ies). At least 50% of the conversations we've had were requesting another Agent to correct the errors of a previous Agent. This was not a matter of being too demanding, or errors on our part. We have several written statements from more competent Agents that action(s) taken by previous Agents were against Viator policy and should not have happened. Once again, all complaints we made against any agent were completely ignored. Worst tour listing company we've ever done business with.
