IF your contract was for a specific room, not simply a specific type of room you may have something. However, any lawyer would need to read your contract first and understand whether your room was in a university controlled housing or simply private housing that rents to students.
Assuming you have a written contract for a specific room, you may have to sue for your room. Before you do that, speak with a LV area landlord tenant attorney, let him/her review your documents and determine what options you may have.
The $7K threat sounds like blowing smoke--you would likely never have to pay the full contract value of the room (and the LL knows that). Speak with a LV LL-T attorney ASAP.
