I booked a trip with Viator. They sent me an email offering me $15 off my next booking in the next 13 days. The website wouldn’t let me use it. When I called in I was told you could only use it with the app. I downloaded the app and it still didn’t work. When I called back they told me it was an invalid code and they wouldn’t honor it even though they sent it to me. The agent kept asking me if I wanted to book the tour any way and I told her I wouldn’t book with a company that what they were doing was false advertising and I wouldn’t book the tour with them. I’m also considering cancelling all of my other bookings. It’s not the $15 as much as their deceptive practices.
