If the training institution maliciously conceals debts and cancels them, which infringes your rights, you can sue the responsible shareholders. You should try to find this educational institution and get relevant information. For example, the company's full name, registered address, legal representative and relevant information of the local adult self-study examination center (including registered place and legal representative), and collect other evidence. If you bring a lawsuit to the court, you are required to refund the tuition fees and claim compensation for economic losses.

After the work of the Consumer Council, more than 95% of the students changed their visas, thus avoiding losses.
