Die Duluth Zephyr Exkursion - Standard Busticket (Reservierung erforderlich)

I wanted to take my family to Duluth for a fun weekend away. It takes us about 3 hours to drive there. I purchased this ticket through Viator and made additional plans for the weekend (which could not be refunded). When I called to select a specific time for our excursion, I found out that this (the Duluth Zephyr Excursion) was not even running on the date I picked, which was in my confirmation email!!! I was able to pick a date and purchase a ticket, even though it was not an option!!! Needless to say, I am furious about this. It was a hassle getting a refund, and I will never do this excursion or make another purchase on Viator again.
