How about iron friend official website? Is it trustworthy?

Although Tieyou didn't cheat money, it was really rubbish. Only the website was beautiful. I planned to travel to Sanya with my friends, and then went to the high-speed rail network (junk website, jumping page). After choosing the itinerary, I jumped to Tieyou. Because I bought a train ticket for the first time, Tieyou reminded us that someone had not checked it, and then several of us went to check it, and it was marked on the 1236 website that it passed the check. After the payment, I said that the result would not be available until 9 o'clock tomorrow. Ok, then I sent a text message the next day saying that we failed the verification, so I gave us a refund, and then the refund would take until the next day. I was so angry at that time. What should I do if the ticket was gone? Then I found that there was an app of 1236, and after I downloaded it, I went to the bank to make up the money. The booking of the 1236app was very fast, which can be said to be very convenient, and there were all the seat numbers. If you can't connect to the seat, you can return it and then set the seat refresh to connect the number. I feel that the existence of Tieyou. com is redundant and irritating.
