We booked a helicopter tour on the last day of our trip through the official site of west rim. On the day of the 28th, it was windy and it started to snow, so the flight time was delayed little by little. The female employee said that if you call the number on the website, they will reschedule or refund you. However, she said that the number written on the website cannot be refunded, and that she will reschedule. Since we had the last schedule for the day, when we asked for a refund, we kept saying that it was operating normally that day. Please sign autographs or make a video. Besides, there is no way to contact them... If everyone is going to the West Rim, make a reservation through a travel agent.
