The property fee has dropped. Before the high price was paid for three years, the property was only returned for two years. If it is unreasonable, you can appeal. Owners can reflect to the property company through the owners' committee, so that the property company can come up with reasonable charging standards. According to the relevant information, according to Article 4 1 of the Property Management Regulations, property service charges should follow the principles of reasonableness, openness and adaptability of charges to service levels, and distinguish the nature and characteristics of different properties. Owners and property service enterprises shall, in accordance with the measures for charging property services formulated by the the State Council price administrative department in conjunction with the the State Council construction administrative department, stipulate in the property service contract.
