You have the right to complain to the higher authorities of the labor inspection brigade, such as the complaint hotline of the Human Resources and Social Security Bureau (formerly the Labor Bureau), the mailbox of the director, the hotline of 12345 mayor, the mailbox of the mayor, etc. In fact, you should go to the labor inspection brigade to complain about social security first. If you can&;t pay it back, you can add a request to the labor arbitration to ask the company to pay the losses you caused, such as unemployment benefits and medical expenses.
