What should I do to buy and sell residential property?

Go to the Consumer Protection Association to complain! This property is too arrogant. I have no idea where it is. If it is in a big city, this kind of thing is hard to happen. If the Consumers Association can't do it, it's better to go to court. It is best for several owners to jointly sue. Personally, I feel that there is a backer behind this property, otherwise he would not be so arrogant!
