Quoting
Mr. Knowitall
If the apartment unit isn't clean when you move in, you should immediately talk to your landlord. Apparently you were able to clean and use the freezer, so it's not clear that that's an issue.
When your appliances don't work, you should immediately contact your landlord and report the problem. You haven't indicated when you reported a problem with your refrigerator to the landlord, or what the landlord's response was to that report. Obviously they won't know that there's a problem until you inform them.
You talk about the water being brown, but you've given us no indication about why it's brown. If it's the same color out of every faucet in the unit, perhaps the problem doesn't originate in the unit. Have you reported the problem to the landlord and, if so, what was the landlord's response? Have you tested the water for safety?
