The company said it overpaid and demanded a refund.

Legal analysis: after the company finds that it has overpaid its employees, it can ask them to return, and employees should also take the initiative to return the overpaid wages. If the employee does not return, it will cause unjust enrichment and need to be returned in accordance with the law.

Legal basis: Article 6 of the Interim Provisions on Payment of Wages, the employing unit shall pay wages to the workers themselves. If a laborer is unable to receive wages for some reason, his relatives or others may entrust him to receive them. The employer may entrust the bank to pay wages. The employer must record in writing the amount and time of employees' salary collection, the name and signature of the recipient, and keep it for more than two years for future reference. When paying wages, the employer shall provide the laborer with a list of his personal wages.
