How did you publish it? Personal agent or online agent! I am a thesis agent, and as far as I know, the core thesis 3500 can't be sent out at all. . . It's too expensive from other provinces. If it is an individual, you can contact this person privately and ask for compensation first, otherwise find a unit and make the whole incident public; If it is online, it doesn't seem easy. You should carefully recall your conversation, determine which journal he wants to send you, and ask which journal and magazine it is and the source of your article. Maybe you can find them this way. If you complain to the relevant departments, you are asking to close the website. It doesn't seem easy to operate. Did you record the call? You must have proof! So it is suggested to find an agent in practice. . .
