What should I do if there is a contradiction between the industry Committee and the property company in order to retaliate against the property industry Committee?

The industry Committee represents the interests of the whole community, and the conflict can only be that the interests of the community are affected! Prove that the industry Committee is responsible. If you retaliate against the industry Committee, You can change the property company by voting by the owners of the whole community. Give a strong backing to the industry Committee. However, the whole society must support the industry Committee.
