Residential property only charges property fees, and does not manage the residential area. How do owners defend their rights?

It's hard to tell the truth. Theoretically speaking, the property works for the owner, no different from the workers you hire. According to the process, you should consult with the owners' Committee and improve it through consultation between the industry Committee and the property. If not, convene the owners' meeting and dissolve the property company. But in fact, the members of the owners' committee are arranged by the black-box operation of the property, and these processes certainly cannot go on. If it is the latter, I suggest you go to the street, go to a few more people, bring as many power of attorney signed by the owners as possible, and let the street arrange to organize all the owners' meetings and re-elect the owners' Committee. But in fact, the street is bought by a property company, which is also difficult to do. In a word, if you want to solve it, you must follow this procedure when you know there is no result. If not, don't be afraid to make it bigger. If it is big enough, it will be solved. One of you should have enough time and energy to push this matter forward.
