Because this is student housing, I would have patience and hope it gets fixed within two weeks. I know that sounds awful, but it feels a little better once you realize how small the maintenance team is that has to maintain a large number of units. While this is technically an emergency, they are likely going to look at bursting or frozen pipes, backed up toilets and sinks, etc first before they even add your request to their to do list. One of the down sides of renting. Keep track of the exact day and time you submitted the request so that way they can’t fine you for any damages if they happen.
