Home Inn has poor hygiene and service. Where can I complain?

Home is not really a drop. The front desk buzzes, like his mother's ancestors. The water dispenser in the room is broken, the water can't be turned on at all, the water in the bathroom is cold, and the toilet can't be used. There are no windows in the room, the air in the room smells bad, and the room has not been cleaned for days. This invoice scratched 50 yuan. Damn it, it's really unreasonable. Home inn is going to close down soon, cheating dad! ! !
