I don't buy social security, but the payroll has social security subsidies.

Legal analysis: you can apply for labor arbitration and ask the company to pay back the money for you or complain or report to the social security department. Social insurance is compulsory insurance required by the state. The state develops social insurance undertakings, establishes a social insurance system and sets up a social insurance fund, so that workers can get help and enjoy insurance benefits in cases of old age, illness, work injury, unemployment and maternity.

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.
