Is Dongguan Juxian Network Technology Co., Ltd. a liar?

I think this is a fraud company. 20 12 a colleague of our company attended their training seminar on behalf of our company, which was originally thought to be a subsidiary of Alibaba. In the process, I lobbied my colleagues to sign an online package for 8800. Colleagues don't want to sign on the grounds that they don't have any money with them, and they also say that they haven't got the boss's approval. During this period, several staff members took it and said that they could deposit 1000 yuan first, but the company disagreed and the money could be refunded. Later lecturer Li went to the company twice to discuss the argument, but the company did not agree, and the money has never been returned. The money was paid by my colleagues themselves, so I can't get it back. The other company called to remind me that the phone bill could not be reached. Li's phone has been connected, but he refuses to answer. On the whole, I was cheated. I really want to sue him in court.
