The property is out of power. What call should I make to complain?

Hello, generally speaking, the property management company has no right to cut off your electricity. I suggest you consult the property management company to see if there is any sudden failure or power outage for line maintenance. If yes, I suggest you check with the property management company about the time to restore power supply, or whether to assist in power outage according to government administrative orders. If so, I suggest you check with the local government.

I hope our answer is helpful to you.
