Go to the social security bureau to complain that the company does not pay social security.

Legal analysis: If the company fails to pay social security, it should go to the local labor bureau or social security bureau. The company doesn't pay social security to employees according to law, so it is suggested to collect the evidence of labor relations between the two parties first, and then ask the employer to pay social security for them at the labor bureau or social security bureau.

Legal basis: Article 57 of the Social Insurance Law of People's Republic of China (PRC) stipulates that the employing unit shall, within 30 days from the date of its establishment, apply to the local social insurance agency for social insurance registration with its business license, registration certificate or unit seal. The social insurance agency shall, within fifteen days from the date of receiving the application, examine and issue the social insurance registration certificate. Where the social insurance registration items of the employing unit are changed or the employing unit is terminated according to law, it shall, within 30 days from the date of change or termination, go to the social insurance agency to handle the change or cancellation of social insurance registration. The market supervision and management department, the civil affairs department and the organization management organ shall promptly inform the social insurance agency of the establishment and termination of the employing unit, and the public security organ shall promptly inform the social insurance agency of the birth, death, household registration, migration and cancellation of the individual.
