How to report the lack of water and power supply in residential property?

First of all. See if the water meter is in arrears. If not, check other places, such as hoses and main gate valves. If not, then the relevant procedures for buying a house are not clear, so there is no supply of housing. Then find relevant civil affairs departments, leaders of residential property departments, and real estate companies, and find these departments with purchase contracts. If not, what will be solved through legal procedures?
