How to report unreasonable property fees?

If the property fee is unreasonable, there is almost no possibility for the owner to report, complain or go to court:

The property fee of the husband's house (renovated house) is determined by the local development and reform commission (price) department; For the purchase of commercial housing, the property company designated by the developer collects the property fee for the first time, and the property and the owner agree in the contract, which is almost a non-negotiable contract; For the old commercial housing community where the industry committee has been set up, the property fee shall be decided by the owners' congress in accordance with the provisions of the Property Law through a double majority vote.

Only when the services of the property management company are not as promised and there are mistakes can they call the local property management association to complain (for example, Shanghai has a property hotline 962 12 1, while Beijing only has a property service guidance telephone number 680 18936-8020).
