Due to poor property management in the residential area, I refused to pay the property fee this year, and the property company cut off the electricity for my home. Is this legal?

First of all, talk about your electricity consumption. If the property company does not sell electricity under this excuse, it is definitely illegal.

In fact, the problem of your car is not included in the property fee, and it is unreasonable for you to refuse to pay the property fee because of this. You can say that you have provided parking spaces in the residential parking property company, and the general parking fee is equivalent to a rental fee. If the property company can prove that it has fulfilled its management responsibility, the general property company is not responsible. Look at the parking agreement between you and the property company. You'd better consult the insurance company for the loss of the car.
