Where can I sue Gu'an housing management company for deceiving people?

Go to the local people’s court to file a lawsuit.

If some leasing disputes are unwilling to be mediated or are unwilling to be mediated, and no arbitration agreement has been reached, the parties may file a lawsuit with the People's Court for the house leasing dispute in accordance with the law.

The coercive force of judgments made through court litigation activities is far greater than that of mediation and arbitration.
