I had problems reserving tickets online.
I bought 3 Berlin Premium Ticket for EUR 81. For my surprise, in the confirmation e-mail, the total price changed to EUR 105! Besides, the voucher shows a 1 day hop-on hop-off in Berlin, instead of 2 days of the Premium Ticket.
Another problem was reserving the Budapest & Vienna Tour Package. Only after the purchase I saw the information that the ticket needs to be redeemed in Budapest first. However, I will be in Vienna before Budapest.
I would like a refund of all tickets.
I filled a contact form in the website on July 30 and so far no one has contacted us to resolve the issue.
