What law did the property company violate by forcing water supply and power failure?

Property companies have no right to cut off water and electricity. The providers of water and electricity are water supply companies and power supply bureaus. Only water companies and power supply bureaus have the right to terminate water supply and power supply through legal procedures. There is no agreement in the contract that the property company has no right to cut off water and electricity for the owner.
