I went to Thailand with the tour guide, went to the so-called royal jewelry market and bought so-called pigeon blood red and pomegranate ruby jewelry. When I came back, I found that it was ordinary gems and garnets. What should I do? Did the travel agency send a tour leader to accompany you when you left the country? If not, the travel agency is illegal. If so, was the tour leader suspected of abetting in the shopping process in Thailand? Did she (he) do a good job of reminding in advance? If the tour guide doesn't remind you of anything, you can go to the travel club to find their boss, explain the situation to him and bring the bill. Because the team leader also participated in the distribution of kickbacks, it is useful to complain within three months after returning. If the travel agency doesn't help you solve the problem, you can even call the tourism bureau. Of course, the premise is that the leader of the group tour does not make any reminders. If he reminds you that you still buy it, there is nothing you can do. Depending on the kindness of the travel agency, help contact overseas agencies.
