My dear Zhou I'm happy to know that now you know how to use you cell phone. Before your arrival I wrote you 12 messages you answered none of them. I also send you the photo of the meeting point you also did not pay attention to it. This day I waited for you 25 minutes and I never wait noone so much time. And you did not come and I left without you. You decided to call me 35 minutes after the meeting time and I was already on tour without you. All my messages to you were recorded on viator app This is for what your refund request was rejected and viator keep your money and did not refund you. This day I also had other guests on your ship they were on time and they meet me, and had a fantastic day with me....Chie chie . Daniel..... I know you will not be able to understand this message I only write it for my next guests.... you can be from china or from America, pay attention to my messages because I will not wait late guests, I will start the tour without you and you will not be refunded
